It has long been known that worn-out tires that are out of service are a potential source of environmental pollution and environmental damage. Recycling tires into crumbs at home is the same popular method, along with factory ones. Rubber waste from used tires is virtually non-biodegradable, taking hundreds of years to decompose.

It should be noted that this rubber waste is a flammable material, and if a huge number of tires ignite, they can pose a threat of poisoning to everyone nearby, since rubber, when burned, releases carcinogenic toxins, such as benzpyrene. Storage in landfills leads to the reproduction of rodents and insects, which are sources of dangerous infections. To avoid the deterioration of the environmental situation in Russia and abroad, proper disposal is required, namely, waste processing. Without constant recycling, an environmental crisis could set in very soon.

Recycling

Recycling is also economically beneficial. From car tires, you can get various types of valuable recyclable materials, as well as produce a huge amount of finished products. From the waste of powder rubber of a very fine fraction (about 0.2 mm), new car tires and rubber shoes are produced, this secondary resource is popular in Russia and the CIS countries.

Powder from waste of larger fractions is used in the production of composite roofing materials, rubber-bitumen mastic, waterproofing materials, and rubber coatings. Scrap metal is obtained from a metal cord, which is also used by Russian entrepreneurs. Also, textiles and rubber are obtained from tires.

Recycling at home

Especially active and advanced people have the opportunity to process rubber with their own hands. What is needed for this? Spent chambers, tires, tires and a little ingenuity. Recycling tires into crumbs at home is a rather complicated undertaking. According to their properties, cameras from old tires are more suitable. They are softer and more easily amenable to external influences.

According to one of the scenarios, the rubber should be cooled to a temperature of approximately -75°C. Agree, not everyone has such an opportunity. So let's use the traditional scenario:

• Take the cameras
• Remove all unnecessary elements from them
• Cut them into thin strips
• Grind those stripes

The rubber grinder in this case is an ax or scissors.

Mechanical processing method

The most professional way. The technological line is a sequence of installed working devices, overcoming which the material becomes a finished product.

Processing into crumb rubber goes through three stages:

1. Tire preparation. Initially, they are washed and cleaned of impurities, after which they are transported by a conveyor to the primary crushing unit, where they are ground with knife crushers to large pieces (30-50 mm).
2. At the second stage of the technological process, the primary processed raw material is fed by means of a belt conveyor to a hammer crusher, where it is re-crushed to smaller sizes (10-20 mm). It is at this stage of processing that the metal and textile cord, bead wire is separated from the rubber. Textiles are separated by a special textile removal system, and metal is separated by a magnetic separator. The collected metal waste is then briquetted.
3. At the final stage, processing into crumbs is already underway. As equipment for processing tires into crumbs, an extruder is used - a grinder, in which the rubber mass is ground into a fine powder. At this stage of tire processing, additional cleaning of crumbs from textiles and metal is also carried out using a gravity separator. After that, the crushed rubber crumb is divided into fractions and packed in polyethylene bags of 20 kg or in big bags (soft containers) with a carrying capacity of up to 1000 kg.

Today, there are a sufficient number of manufacturers of this equipment on the Russian market.

Chemical processing method

With the chemical method of processing, automobile tires are subjected to pyrolysis. With this processing method, the thermal decomposition of rubber into its constituent elements occurs. Tires are pre-crushed into a homogeneous mass and sent to an oven, where they decompose at a temperature of 500 - 800 ° C. This procedure lasts 10 - 20 minutes. In the process of thermal decomposition of rubber, about 50% hydrogen and 26% methane are formed, as well as solid pyrolysis products, which are then used in wastewater treatment at wastewater treatment plants in Russia.

There is also an effective, but expensive physical and chemical method for processing tires into crumb rubber - cryogenic grinding of car tires. Crushing of rubber is carried out in a special cooling chamber at extremely low temperatures (up to - 120 ° C). A refrigerant (liquid nitrogen) is supplied to this chamber, cooling to ultra-low temperatures. In conditions of strong cooling, the rubber acquires a glassy state. Crushing of rubber occurs when struck with a special hammer. After grinding, textiles and metal are removed from crumb rubber.

In modern times, there are many mini-factories for the processing of tires. The business plan for recycling car tires is quite simple. Its implementation will require modern tire recycling equipment, warehouse equipment, fuel tanks, tools and overalls for workers, as well as equipment installation costs. It is necessary to register an enterprise and a license that will allow you to engage in this type of activity. Starting this business will require significant start-up capital.

Reforms in the field of environmental protection, which began to be implemented in recent years, are gradually being tightened.

What should natural resource users expect? A complete ban on the disposal of waste tires and car tires is introduced.

This position of legislators should stimulate the development of the industry recycling of waste, the opening of new industries for their modification.

Deserves close attention. A low-cost, easy way to process tires requires the use of special equipment.

Let us consider in more detail the popular types of machine tools and the production lines formed from them, the characteristics of these units and how much they cost.

The technology for the production of rubber crumb from used machine tires is a process of successive grinding of raw materials into small pieces, followed by grinding them into a fine fraction.

Manufacturers offer a wide range of machines for the production of crumb rubber, prices depend on the performance of the equipment.

Single shaft shredders

The principle of operation of a single-shaft plant is based on the grinding of raw materials successively lowering and rising low-speed cutting shaft.

The operation of a rubber shredder is as follows:

1. Tires are fed into the chamber of the raw material loading shredder, where, under the action of a hydraulic press, they are fed to rotating knives.
2. The press moves from top to bottom, returning to its original position after reaching the maximum degree of pressure on the shaft.
3. The crushed raw materials are pressed through special sieves placed under the shaft.

Fastening double-sided knives to screws allows them to be reused after one of the edges is worn out. This design feature allows increase standard service life tire crushers.

Among the advantages of single-shaft rubber shredders, the following can be distinguished:

• simple design;
• ease of operation;
• the possibility of individual use and inclusion in the production line;
• processing of thick raw materials.

An example of such equipment is a single-shaft machine for processing rubber and tires into chips from Netmus; the price of the presented equipment varies in the range 120,000 - 2,800,000 rubles.

Twin shaft rubber shredders

Two-shaft tire shredders are designed for cutting raw materials into pieces no larger than 5x5 cm. The shredder blades can process tires from both passenger cars and heavy vehicles.

Principle of operation machine as follows:

1. A tire is fed into the raw material receiving chamber. The size of the window allows you to load the entire product, the only requirement is the preliminary extraction of the cord.
2. The shafts of the tire grinder into crumbs rotate in opposite directions. Hooks placed on the rotors grab the raw material and tear it apart.
3. The crushed raw material is sifted through a sieve, which is a rotating drum. Particles that exceed the size of the sifter cell are thrown into the loading chamber for re-processing.
4. The finished material after sorting into fractions falls on the conveyor belt and is fed to packaging.

Benefits of using twin-shaft machine for the production of crumb rubber:

• the possibility of processing large-sized raw materials;
• no need to regrind the blades of the knives when reinstalling them.

The performance of the rubber processing machine directly depends on dimensions end products. So, in the manufacture of tapes and pieces measuring 5x5 cm, the output of 1 machine will be 2 tons / hour and more, with more thorough grinding - up to 2 tons / hour.

No special skills are required from the personnel serving the machines.

The number of auxiliary workers to work in 1 shift is 1-2 people: 1 person for loading raw materials, 1 person for receiving finished products.

Two-shaft tire crushing machines are supplied by the Russian company TechnoService LLC.

Tire Shredding Plant

Let's consider tire shredding installations on the example of UPSHK equipment from the Tekhnoresursy company.

The installation is a rotating crown with 25 knives mounted on it, brought to a tire clamped in a special cartridge.

Manufacturing process as follows:

1. Feeding the tire to the clamping drum.
2. Installing and fixing the tire in the drum manually, or using the lifting mechanism of the installation.
3. Turn on the drive and start rotating the drum. The unit control system provides 3 rotor speeds. It is advisable to choose them depending on the outer diameter of the tire.
4. Approach of the cutting crown rotating in the opposite direction in relation to the drum. The speed of movement of the crown is set by the attendants and depends on the desired size of the fraction of the finished product - the slower the movement, the finer the rubber crumb.

Rubber is removed from the tire, starting with the outer layer, and before reaching the layers of the cord.

Textile cord can be crushed together with rubber, metal cord is the boundary beyond which the use of the machine is prohibited.

Benefits of using the machine:

• successfully replaces the whole tire shredding line;
• competitive price;
• ease of transportation;
• fast installation;
• instant connection to the power supply system;
• the possibility of processing tires of various sizes;
• short payback period.

Maintenance of the installation is carried out by one worker. The production technology itself is very simple and does not require additional training.

For a month, one installation is capable of producing 34 tons of clean rubber crumb.

Prices for such equipment for processing rubber into crumbs start from 770 000 rub.

lines

Integrated approach to problem solving tire recycling is provided by lines for grinding used tires into crumbs.

The complete set of equipment offered by various manufacturers differs little from each other:

• bead ring removal device;
• guillotine for grinding tires into a tape;
• machine for squeezing steel cord;
• rollers for the manufacture of crumb rubber;
• magnetic and air separators;
• vibrating sieve.

Technology tire processing is as follows:

1. Separation of tires by weight and diameter, cleaning from large contaminants.
2. Installing the tire in a vise to separate the bead ring from the rubber.
3. Cutting the resulting rubber into ribbons about 4 cm wide.
4. Dividing strips into small pieces.
5. Grinding blanks into crumbs with subsequent supply of products to the conveyor.
6. Product cleaning in the separation chamber. With the help of the magnetic fields created by the installation, the metal cord particles are separated from the total mass of the crumb. In the air cleaning chamber, due to the formed vortex flows, the final separation of impurities from rubber particles occurs.
7. Sorting of the obtained products into size fractions.

The finished crumb is packed and can be sent for sale. Larger particles are returned to the conveyor and subjected to repeated grinding.

The line capacity is from 500 kg of raw materials per hour.

To maintain the line, 2-3 people will be required for 1 work shift, while special training in the skills of working with the equipment is not required.

On the market of production equipment, tire processing lines are represented by manufacturers from different countries. Consider the distinctive features of individual brands of equipment.

Tire processing line from the Novokuznetsk company ALPHA SPK "ATR-250" declared by the manufacturer as fully automatic. Human participation is required only if it is necessary to grind especially large tires. Equipment price starts from 5,000,000 rubles. You can study the supplier's offer in more detail on the website.

Factories

Mini-factories for the production of crumbs from rubber tires are the best option for those who want to organize the processing of raw materials on a large scale.

Such production will have not only a personal, economic, effect, but also a social one.

New jobs will be created, social tension will decrease.

Benefits of using mini-factories for the production of crumb rubber:

• low energy consumption, and hence the cost of produced crumbs;
• compactness;
• ease of maintenance;
• excellent quality of grinding raw materials, allowing you to set up production in one cycle;
• environmental friendliness.

With the increase in the number of road transport as a result of an increase in the volume of waste, the issue of the environmental situation has become acute. Every year, thousands of tires are taken to landfills and landfills, where they become a source of negative environmental impact.

Car tires belong to the 4th class of hazardous waste due to the carcinogenic and toxic substances released during the decomposition process, which destroy the biosphere shell. In recent years, the requirements for waste disposal in large cities have become stricter, and compliance with the technique of processing rubber products is regularly checked.

Fire safety regulations prohibit the storage of tires due to the possibility of spontaneous combustion. An active person with basic knowledge of physics and carpentry skills can turn rubber waste recycling into a main source of income. Rubber crumb, obtained in the process of recycling, acts as a secondary raw material in the manufacture of goods.

What is crumb rubber made from at home?

Rubber crumb is made from worn-out car tires, they are better amenable to mechanical stress and the extraction of metal wire (cord). Recycling used tires allows you to get a crumb of the required diameter with minimal loss of raw material. Volumetric figures carved from tires are used as decoration in the courtyards of housing estates or garden plots. Often you can find flower beds, low fences, fences for playgrounds made of tires.

Rubber crumb of large sizes lay out the paths of private houses and summer cottages, giving them an aesthetically beautiful look. Rubber coatings with waterproofing and noise-absorbing properties are equipped with playing areas and sports grounds.

Recycling small amounts of rubber at home

Getting a small amount of rubber crumb for personal use does not require a large amount of raw material and special equipment. You can use improvised means, such as scissors, a guillotine cutter or an ax. A well-sharpened knife is also suitable for cutting old tires.

Stages of processing tires into crumbs at home:

• cord removal
• cutting waste tires into strips
• grinding of obtained raw material

Dealing with large volumes of rubber waste for commercial and personal purposes requires financial investment, the purchase of equipment and the availability of a facility for the processing of raw material. The cost of units offered by manufacturers depends on their capacity and configuration. Domestic and foreign manufacturers provide complete cycle rubber waste processing lines. Having a basic knowledge of physics, you can make equipment for processing tires into crumbs with your own hands that meets personal needs.

Methods for making crumbs from tires

Methods for obtaining rubber crumb:

• Cooling of raw materials with liquid nitrogen to a brittle state and subsequent grinding. This type of processing requires special freezers, the raw material is cooled to a temperature of -70 - -90 degrees and is impossible at home.

• Grinding of rubber products on specialized lines of a full cycle of processing. This method is used in industrial production, where the production of crumb rubber is carried out on a large scale and requires large financial investments.

• Recycling rubber at home on home-made units (crushers). With milling and welding equipment, you can make a chopper with your own hands. In the absence of such an opportunity, parts can be ordered in the workshop according to personal schemes. The cost of a self-made crusher is much cheaper than finished equipment.

Regular recycling of waste rubber requires a well-ventilated and spacious room to install equipment and store a large amount of waste rubber. The location of the premises in the industrial zone will be a plus.

Unit device

The design of the shredder is a knife mechanism (shredder), which allows you to process tires, tubes and other rubber elements. The material with this method of grinding retains its molecular formula and does not lose its elasticity properties. The performance of the equipment depends entirely on the indicator of its power.

The main components of the rubber processing unit:

• Electric motor - ensures the speed of processing rubber waste, the recommended engine power is 4-5 kW.
• Box with cutting discs - grinds the raw material to the required size.
• Grid for grading the crumb - regulates the diameter of the resulting crumb rubber.
• Worm gear - eliminates jamming and jamming of material.
• Frame of the unit - provides a stable position of the machine.
• loading hopper
• Guide tray

The entire mechanism of the machine is placed in a housing, on top of which a loading hopper is installed. Before loading the material, foreign metal objects (thorns, nails, etc.) must be removed. Tires are cut into strips reducing recycling time.

Box with cutting discs

The main part of the unit is a shredder. The box contains high strength heat treated steel milling discs. They are quite wear-resistant and do not require frequent replacement during machine operation. The manufacture of the structure requires an accurate calculation of holes and cutting discs, so the work should be entrusted to the designer.

Grid for crumb calibration

A sizing grid is installed under the box with milling shafts, which allows you to adjust the diameter of the rubber crumb obtained by shredding tires in a shredder.

Worm gear

The mechanical gearbox converts the angular speed using a worm gear and allows processing rubber material of various elasticity without winding and hanging. The mechanical transmission of rotational movement is set in the range from 25 to 35 units, providing high performance of the unit.

Machine frame

Safe operation is guaranteed by the frame of the machine, made of profile materials. It ensures the stable position of the unit during the grinding and loading of the raw material.

The machine is equipped with a hopper for loading tire raw materials, which for convenience is located on the upper part of the body and a guide tray. They provide a uniform flow of raw material into the shredder (chopper) preventing the formation of congestion during operation.

Tire cutter

To cut the tires and remove the metal cord, a rack and carrier frame design is used. The body houses the bar clamping system, which rotates with the bar during cutting. The rack of the structure is equipped with a wedge-shaped knife, adjustable to a specific tire size. This technology of mounting the structure saves time on preparing consumables for further grinding in the shredder.

Tire shredding

The technological process of grinding involves the following procedure:

• Sorting of tire raw materials and removal of foreign metal (nails, spikes, etc.)
• Removal of metal cord
• Cutting tires into strips
• Grinding of raw material in a shredder
• Calibration of the resulting crumb

Recycling

Rubber crumb is widely used in various fields of production, sold to the public or used for personal purposes. An excess of worn-out car tires and rubber products ensures the constant availability of consumables.

The cost of crumb rubber depends on the diameter and quality of the granules. Powdered crumbs and granules with a diameter of 2-4 mm are in great demand. The popularity of this size is due to lower costs for the production of goods and lower consumption of adhesive, the price of which exceeds the cost of secondary raw materials several times.

Rubber crumb is used for the manufacture of the following products:

• Roll coverings
• Rubber Shoes
• paving slabs
• Fuel
• Rubber insulation and seals
• 3D figures carved from used tires
• Paths for private houses, garden and summer cottages
• Waterproofing and noise-absorbing coatings for children's and sports grounds
• Rubber technical products
• Asphalt mixes
• Seamless rubber flooring

Currently, the recycling industry is considered promising for starting your own business due to low competition and growing demand for waste processing services. Even with a small amount of work performed, the financial investment spent on equipment pays for itself in a short time. Recycling tires in a tire crusher is recognized as the most environmentally friendly recycling method that allows you to make a profit with a small financial investment.

Every year, thousands of tires go to landfills and landfills, despite the fact that for an enterprising person they are a free resource from which crumb rubber can be produced.

If it was needed only once, you can buy it in the right amount from manufacturers.

But where can you get crumb rubber if you need it on an ongoing basis and in large quantities?

Consider purchasing your own tire recycling equipment.

However, not everyone can afford a full-fledged installation, and such an investment will not be profitable for everyone. The way out is to create equipment with your own hands, and use it to produce crumb rubber from tires at home.

Recycling small amounts of rubber at home

If you need very little raw materials, you can do without equipment at all.

This will require only scissors and a cutter.

The metal cord is first removed from the tire, then it is divided into strips and crushed into smaller fractions to the required size.

At this point, the process is considered complete.

Material for the design of paths, flower beds or a separate playground is ready to use.

But to get more raw materials or have an income from tire recycling at home, you need the right equipment.

Tire crusher construction

Three main methods of crumb production are used:

1. Tire crushing after cooling with liquid nitrogen to -190 degrees.
2. Obtaining crumbs on industrial equipment of a full cycle with the removal of the cord and subsequent grinding of rubber.
3. Recycling using universal crushers, which you can do yourself at home.

The first two methods require large investments. The third option is available to anyone who has the ability and desire to make a crusher at home.

The necessary units can be made independently in the workshop or at the production site - where there are metal-cutting machines (turning, milling) and a welding machine for the manufacture of component parts.

If it is impossible to perform the machining of blanks on your own and you have to order them according to your own drawings, the cost of tire processing machines will still be several times cheaper than similar purchased units.

The main component of the tire recycling line is a shredder (rubber grinder). Let us consider in more detail the purpose of the nodes of this machine.

Unit device

The machine consists of the following main units:

• electric motor 5 kW - 2 pcs;
• housing with disc shafts;
• lattice;
• worm gearbox - 2 pcs;
• shredder frame;
• loading bunker;
• guide tray;
• control cabinet.

Details of the installation are mounted on a powerful frame welded from channels.

Box with cutting discs

The main unit of the crusher for rubber is the body with milling rolls.

At the same time, the cutting knives are made of high-strength steel and heat-treated, which significantly reduces their wear. They practically do not require sharpening during operation.

The calculation of the openings of the box, shafts and cutting elements must be accurate, so it must be done by a specialist in this field (designer).

Grid for crumb calibration

In order to obtain a calibrated fraction of tire raw materials, shredders are equipped with a special grate, which is installed under the rolls.

Worm gear

The rotation of the shafts with disk cutters is carried out separately, directly from the worm gearboxes connected to the electric motors through couplings.

The gear ratio is selected from 25 to 35 so that the cutting is without sticking and at a sufficient speed.

Machine frame

The frame is welded from profile elements, ensures the reliability and stability of the unit during operation, as well as loading and unloading operations.

loading hopper

The tire recycling plant is equipped with a tire loading hopper and a tray for removing finished crumb rubber.

Thanks to its design, the hopper eliminates the formation of blockages from the raw materials and guarantees a directed movement of the mass towards the rotating rolls.

Tire cutter

The tire cutting and cord removal plant consists of a carrier frame and a stand.

On the carcass is a tire clamping mechanism that rotates with the tire during cutting. The engine speed is reduced due to the different diameter of the pulleys. There is a built-in wedge-shaped cutter on the stand, which is adjusted to a certain size by moving the quill.

How to grind tires?

The technological chain consists of several preparatory stages before the production of the required fraction is obtained.

This procedure includes:

1. Inspection and removal of foreign objects from the tire cavity.
2. Cord cutting.
3. Cutting the tire into strips of 50-80 mm in size.
4. Grinding of raw materials by means of a shredder.
5. Separation and separation of metal from textile parts.
6. Calibration of crumbs into fractions using a vibrating sieve.

Equipment performance

The work of these two main units during the processing of tires is done in a semi-automatic mode.

For the normal operation of this line, a room of about 150-200 square meters is required. meters. This is due to the fact that you need a place for the location of not only equipment, but also for storing worn tires, finished tire products and metal waste.

The output of rubber crumb on this equipment per hour will be approximately 200-800 kg and up to 100 kg of scrap metal, 2-3 unskilled workers will be needed to service the machines.

In addition to tires, this equipment can process other rubber (conveyor belt, cameras, gas masks). The output is a crumb with sizes from 0.7 to 4 mm, while it is 65-85% of the total mass of raw materials.

Where to apply the obtained raw materials?

Rubber crumb can be:

The price of crumbs will depend mainly on the quality of raw materials, and secondarily on the fraction.

The most popular is the crumb, the fraction of which is 2-4 mm.

It's great for creating:

The popularity of such crumbs is due to the fact that the minimum amount of glue is used to glue these granules. A polyurethane binder is sometimes 5-8 times more expensive than crumbs.

Conclusion

Building a DIY tire crusher is a good idea for those who want to make their own rubber crumb but aren't ready to spend tens of thousands of dollars on equipment.

You can create a chopper with a carpentry workshop, as well as certain skills and materials, or use the services of people who specialize in this.

The crumb obtained at home can be used for your own needs or sold to enterprises and the public.

Making rubber crumb with your own hands at home

In recent years, the use of crumb rubber and materials made on its basis for decorating sites, organizing paths, and covering roofs of houses has become fashionable. You can also use crumb rubber to create waterproofing for building foundations. In order to use crumb rubber elements on your site, you can contact a company that professionally works with crumb rubber. However, working with this material is not so difficult. If desired, and if you have free time, crumb rubber can be made at home with your own hands.

What is rubber crumb made of?

There are two ways to go about solving this issue. Path number one relies on the transition of rubber to a brittle state at low temperatures. If at home it is possible to cool the source material for preparing crumbs to a temperature of -70 ... -80 degrees Celsius, then it will be possible to obtain crumbs from any type of source materials. However, solving this problem at home is not so easy.

Path number two is the competent selection of source material. As we know, crumbs can be obtained from tires and tubes from car wheels. But tires are very difficult to grind under normal conditions, and it is also difficult to extract the metal cord from them later. For this reason, to obtain crumb rubber at home, it is better to use old worn-out cameras as raw materials. This material can be easily cut with the help of improvised tools available in any home.

How to make crumb rubber at home?

At the initial stage, it is necessary to prepare a sufficient amount of raw materials, i.e. old car cameras and the appropriate cutting tool. For the manufacture of a coating with an area of ​​​​one square meter and a thickness of 10 mm, about 8 kg of crumb rubber is needed. In the production of crumbs from old chambers, the loss of material by weight is minimal. Thus, it is necessary to prepare the source material at the rate of 8 kg of old cameras per 1 square meter of coverage.

To grind rubber, you can use ordinary scissors or an ax. If desired, you can build special guillotine shears. In extreme cases, you can organize the cutting of cameras with a fairly sharp knife.

Crumb production must be performed according to the following algorithm:

• Remove all metal elements from the old camera
• Cut the camera into thin strips
• Thin strips obtained in step 2 grind

Tire recycling at home

Every motorist knows that the disposal of used tires is a serious problem. However, recycling tires at home has several options. Let's consider some of them.

Creativity

There are many examples of the creation of original sculptures from used tires, used to decorate the garden, or as an independent work of art. Garden variations can be embodied in the form of swans, garden vases, etc.

The "pattern" is extremely simple and understandable. And the created images are very similar to living prototypes.

There is also a more artistic attitude to rubber waste. From them, as from clay, the conceived sculpture is literally “molded”. You can, for example, sculpt a horse, and, moreover, such a hot one that will cause the approval of other venerable sculptors.

Pragmatic Approach

Yet for most, tire recycling at home involves the use of waste rubber for the benefit of the home and its economy. There are several nuances here.

Firstly, you can use used tires for the home, as they are.

Secondly, the product of their primary processing obtained at small and large enterprises can be used in the household.

Thirdly, it is possible to organize a production within the framework of a private, home-based company, which is engaged in the actual primary processing of tires.

Using tires as an eternal material

Tires are known to be one of the finest building materials. Some craftsmen used tires from Belaz as a support, a foundation under a garden house. And prudent owners can use tires as elements:

• fence
• mini flower beds
• playground elements

Application of partially recycled rubber

Tire recycling is carried out in stages:

• cutting and crushing
• plasticization and exit to the final product

Crumb rubber is a semi-finished product used for various types of production. You can make fuel out of it, or you can make tiles, moreover, both for asphalt and for roofing. It is also used for the production of shoes, sports ground surfaces, etc.

In the household, you can even use a crumb in the form of a semi-finished product - it is sprinkled with paths along the lawns. You can also use rubber roofing for your home.

Waste tire recycling

Tires are crushed - either in a state cooled to -70 ... -80 degrees, when the rubber becomes brittle, or at normal temperature - but with a more powerful tool. To obtain fuel, rubber is subjected to a pyrolysis operation.

This is an environmentally hazardous process. Equipment, space maintenance, organizing the collection of raw materials and finding buyers, attracting significant funds - all this is completely associated with a small "private shop" where tire recycling would be profitable.

Conclusion

As part of a car enthusiast's household, recycling tires is quite difficult. To do this, you need to be a very big enthusiast. But maybe you will be lucky enough to find a unique way to use bad tires.

technology for processing car tires, tires and other rubber, description and video of the manufacturing process

The service life of car tires is quite short, after which they must be replaced.

Disposal of worn-out tires is a big problem for the ecology of the whole world.

Every year the number of used cars increases by almost 10%.

Obviously tires need to be recycled.

In this article, we will consider the following questions:

• what is the technology for processing crumb tires;
• what equipment is used;
• where rubber crumb is used;
• Is it possible to make it yourself.

Tire recycling methods

Not only worn-out tires, but also any other used rubber products can serve as raw materials for rubber crumb production.

In practice, only two main methods are used to obtain crumb rubber from used tires:

• shock wave;
• mechanical.

Let's consider both methods separately.

shock wave

This technology for grinding car tires and other rubber waste into crumbs was invented relatively recently.

The processing process consists in cooling products to ultra-low temperatures, followed by crushing by a shock wave.

Cryogenic chambers are used for freezing, and the shock wave is formed by a special electrical device or by detonating a small amount of explosive.

This technology for recycling used car tires requires the installation of expensive equipment, which is economically beneficial only for large enterprises with large volumes of raw materials.

Mechanical

This is a classic technology for processing tires into crumb rubber, which, unlike the first, is used everywhere.

The essence of the process lies in the phased mechanical action on the raw material to obtain the required fraction of crumb rubber and by-products.

There are several methods for recycling tires by mechanical action:

• grinding at normal temperature;
• at high temperature;
• with cooling of raw materials;
• using the "ozone knife";
• by forcing raw materials with a powerful press through special dies.

The most popular method is conventional mechanical grinding at normal temperature.

This technology is classic and is great for organizing small enterprises for recycling used car tires.

Classic tire shredding technology

With the necessary equipment, this technology makes it possible to obtain crumb rubber of any fraction up to a dusty substance.

The whole tire recycling process can be divided into several stages, each of which uses a certain type of machine tools and mechanisms.

The main technological stages of crushing tires and the types of equipment used in each of them:

1. At the first stage of processing, tires are sorted by size, which is necessary to adjust the equipment for certain tire sizes. Crushing itself begins with cutting the side rings on a special punching machine.
2. The second stage of tire shredding takes place using hydraulic shears, mechanical cutters or guillotines, which are used to cut into strips and pieces of medium size.
3. The crushing process continues in a special shredder, where large pieces of rubber are crushed into small chips ranging in size from 2 to 10 square meters. cm, which arrive at the next technological operation.
4. At this stage, the final grinding of raw materials to the required fractions takes place. Rotary mills with square blades or other equipment capable of withstanding enormous mechanical loads are used.
5. After complete grinding of used tires, it is necessary to separate the resulting crumb rubber from by-products: chopped metal court and textile waste. For this, magnetic and air separators are used.
6. At the final stage, the resulting rubber crumb is passed through a special vibrating sieve, where the separation into fractions takes place. The resulting material is packaged and sent for further processing.

This is the classical scheme of the technological process of crushing tires into crumbs at normal temperature with an approximate list of machines and mechanisms.

The number of processing stages can be reduced or increased depending on what equipment will be used and what kind of crumbs you need to get at the exit.

Transportation of raw materials from one technological operation to another can be carried out both manually and automatically.

If the movement of tires, pieces of rubber, chips and crumb rubber is carried out using belt and screw conveyors, then the whole complex of equipment for recycling old tires, in fact, becomes a production line.

For the organization of a small recycling workshop, the installation of an automatic line is the best solution.

What equipment is needed?

There are a lot of offers on the tire recycling equipment market.

Russian and foreign manufacturers offer both fully equipped lines and plants, as well as individual machines, devices and mechanisms. The price will depend on the type and performance of the unit.

Consider the minimum set of what is needed for recycling tires into crumbs.

Bead removal machine

This is the first unit in the entire technological chain of tire grinding. Its purpose is to remove the landing rings from the tire.

The principle of operation of bead removal machines is based on:

• cutting down;
• cutting;
• pulling out the landing rings.

Each of the methods does not have any advantages over the others.

Further processing of the removed rings is carried out on pressing machines, where the metal base is squeezed out and the remaining rubber is crushed in the general flow.

Tire shredders without bead

• shredders;
• tape cutters;
• hydraulic shears;
• roller milling devices;
• mills.

The production line may include several such devices:

1. Hydraulic shears and tape cutters cut tires into large pieces.
2. Shredders process them into smaller fragments.
3. Roller aggregates and mills bring the type of raw material to the required fraction.

Metal and textile separators

The magnetic separator removes the chopped remains of the metal court from the crumb rubber.

The principle of operation of this device is simple: a powerful electromagnet pulls metal waste from the mass of raw materials and sends them to a receiving hopper.

Removal of textile residues takes place in a cyclone-type air separator, where a powerful air stream simply blows light textile fluff into a receiving hopper.

Read more about textile and metal cord, as well as where it can be used with benefits, read here.

Vibrating screens for separating the product into fractions

Tire recycling complexes include at least two vibrating screens: coarse and fine cleaning.

On the first device, large, not completely processed, pieces of rubber are screened out, and on the second, the standard fraction of rubber crumb is separated.

A vibrating sieve is a device consisting of a table with holes corresponding to the crumb fraction to be separated, and a mechanism that vibrates the table at a certain frequency.

Conveyors and other mechanisms and devices

Tire recycling lines and plants include belt conveyors to move tires, pieces of rubber and crumb rubber from one process step to another.

Some manufacturers use screw conveyors in their lines to move and pack finished crumb rubber. In addition, automatic tire recycling lines are equipped with bunkers, security systems and process control.

All of the above equipment is equipped with automatic lines for processing old tires into crumb rubber.

The number of machines and mechanisms depends on the volume of production and the final type of product that needs to be obtained as a result of processing.

What can be made from the obtained granulate?

Crumb rubber itself, obtained by recycling old car tires, is an intermediate product. Raw materials, depending on their fraction, are used in the manufacture of the following products:

• floor coverings for indoors and outdoors;
• curbs, bumpers and speed bumps for road facilities;
• substrates and pads to protect goods during transportation;
• figures for playgrounds;
• building materials - waterproofing and noise-absorbing;
• dielectric products for the electrical industry;
• MBR - bitumen-rubber mastic.

Granulate is also added to asphalt mixtures, obtaining a strong and durable road surface.

From fine crumbs, it is possible to produce various rubber products by hot pressing, namely:

• bushings;
• rollers;
• rubber shoes;
• many other goods.

In addition, it can serve as an additive in the manufacture of new tires, thereby reducing its cost.

The entrepreneur receives not only rubber crumb, but also grinding by-products: metal court and textiles, which are also liquid goods. They can be sold and get additional profit.

As you can see, there are ample opportunities for the tire recycling business in terms of marketing products, because the need for it is very high in many industries.

Making crumbs from tires at home

Tire granulate can be easily purchased in online stores, building supermarkets or ordered directly from the manufacturer.

But for those who want to open their own small home business or just make a pavement for the paths in the garden with their own hands, the issue of self-production becomes relevant.

In this case, it makes no sense to purchase expensive equipment for the processing of tires.

There will be no problems with raw materials for making rubber crumb at home. It is enough to walk around the neighbors, who will gladly take out the used tires from the garage and get rid of them.

The simplest set of equipment and tools for grinding tires and other rubber products can be made by hand with minimal investment.

As mentioned above, rubber can be crushed mechanically or by freezing to a low temperature.

The latter option for the home is unacceptable, since it will be necessary to purchase an expensive low-temperature chamber to cool the raw materials.

For the home, the best solution would be mechanical cutting and grinding rubber to a crumb state. In a separate article, we told how to make equipment for these purposes.

One of the manufacturers made an interesting and informative video about recycling tires into crumbs, we offer you to see the process with your own eyes:

Conclusion

Rubber crumb is a multifunctional material necessary for a person in many fields of activity. Its huge plus is that it can be made from old tires, thereby giving a second life to obsolete products.

Recycling rubber is easy, equipment for this purpose is available everywhere.

How do you think, how can you make money on some types of household waste, not counting, of course, services for its disposal? For example, on old, unnecessary car tires? It should be noted that there are really a lot of options.

Just like plastic bottles, tires can be used to make garden decorations (flower beds, animal figurines, swings, sculptures, and much more). In general, collecting (or buying up) and recycling car tires turned out to be a very profitable business, especially if you approach it with a certain amount of imagination and using various modern technologies.

Based on the fact that such a large amount of raw material remains unclaimed, it can be said that competition in this type of business is relatively small, even miserable. And finally, the most important thing is that the products obtained as a result of the processing of automobile tires are in high demand now, and will be in demand for at least another hundred years. So, if you wish, you can pass your established business to your grandchildren.

People have long begun to think about the recycling of used tires from cars, which increase by a huge amount every year. But no solution has been found. Of the total number of used tires, only a fifth is recycled. There are only recycling points for these old tires. By helping to improve the environment, you can earn extra money on this.

Worn-out car tires are quite valuable polymeric materials. A ton of used rubber contains about seven hundred kilograms of rubber that can be reused, for example, as fuel, various rubber technical products and building materials.

At the same time, if such a ton of tires is burned, then two hundred and seventy kilograms of soot and four hundred and fifty kilograms of toxic emissions will violate the environment. It is unprofitable and very difficult to recycle tires economically on the scale of a large industry. But, according to manufacturers of mobile equipment for recycling, such production in a mini-enterprise can be a huge success and a good profit.

Such a small factory is a prefabricated equipment, which covers an area of ​​about eighteen square meters, its height is ten meters. This equipment is capable of processing about five tons of consumables per day.

Moreover, the production area includes warehouses for worn materials (plastics and tires), an area for the preparation of raw materials (cutting tires into pieces), as well as a warehouse for finished materials such as liquid fuels, carbon black, and scrap metal storage.

What can be obtained from the old "rubber".

What is most surprising is that the process of recycling automotive rubber is itself a final process, leaving almost no waste behind. Let's see what you can get as a result of recycling old tires:

Rubber crumb, which is used in the production of various gaskets and seals (including for sanitary purposes), shoe soles, rubber mats, rubber roofing (you can find out about liquid rubber for roofing here), Novotek seamless coatings, as an additive to asphalt , filler for punching bags, and for many other purposes.

Equipment for recycling tires and rubber to the plant: installation

The need to recycle used tires arose due to the rapid growth in the number of cars in most developed countries. The number of used tires is growing every year, so the problem of their disposal has become an acute problem for the authorities of the states. Tire recycling equipment is not cheap.

Special factories and enterprises for their processing are being built. They solve the environmental and economic problem associated with the disposal of obsolete car tires. This waste tire business is already growing by leaps and bounds today. First of all, this is facilitated by a large amount of inexpensive raw materials.

A tire processing plant is being built near the place of sale of the product obtained after processing, namely: rubber crumb, saw, steel cord, fuel oil. A tire recycling plant is a cost-effective solution to the problem. It is located at the place of accumulation of raw materials or near the plant, the production in need of recyclables. The main thing is that the tire recycling plant should be located at a distance of more than 300 meters from the located residential buildings.

The plant is equipped with special equipment for the production of crumb rubber. To open a business in this area, investments are needed, however, due to the small number of competitors and the demand for this raw material, all investments pay off in the near future.

Waste Tire Recycling Equipment

Equipment for rubber processing is a plant - a reactor. It is installed in a specially designated open area.

Medium tire shredding equipment has the following capacity:

• 2 tons of liquid fuel
• 1.5 tons of solid residue containing carbon
• 0.5 tons of steel cord
• 1 ton of gas

The volume of tires to be shredded is 5 tons per day. Processed products serve as raw materials for many types of production. The reactor itself operates using gas, which itself is capable of producing during the processing of used tires. The installation is low maintenance, it only needs two people for one shift. To work on such a plant, employees of the enterprise need to undergo special training and study the features of the process.

Tire recycling products include:

• Rubber granulate and crumbs. Rubber crumb comes in various fractions: 0.1 - 0.45 mm.
• Regenerate. Finely ground crumbs with improved quality. Dimensions: 0.6 - 10 mm.
• Crisps. Size 2 - 5 cm. Represented by pieces of tires along with steel cord.
• Resinoplast. Used in the manufacture of soft roofs.
• Rezinopol. Represented by a floor polymeric covering.
• Bireplast. It is represented by a multi-layer waterproofing roll roofing material.
• Reisol. Represented by rubber with a waterproof adhesive layer of rubber.
• Fiber concrete. A mixture of crumb rubber and two types of cord: textile and metal.

Rubber processing technologies

Rubber recycling can be done in several ways. The choice of method ultimately determines the appearance and demand for the resulting product. The paragraph will not deal with landfilling. Despite the fact that this option is the simplest, at the same time, the crumb plant causes the least harm to the environment.

There are four main recycling methods:

1. Crumb production - equipment for the recycling of tires into crumbs is considered the most rational, it can process several tons of tires per year and brings a stable income to the owner. But the technology is not perfect, it has a significant number of disadvantages, such as the need to select raw materials with the same composition to standardize the properties of the final product.
2. Pyrolysis is the decomposition of tires under the influence of high temperature. This method is extremely inconvenient because during this process a huge amount of toxins released into the atmosphere is released. Another obvious disadvantage of this method of disposal is economic unprofitability. Decomposition equipment is expensive and pays for itself in a significant amount of time.
3. Incineration - is the complete destruction of tires. The only benefit from such an action is the production of energy, however, such products do not act very well as fuel. This is due to the fact that during combustion a large amount of soot is formed, which over time makes the equipment (furnaces) unusable. Since rubber contains sulfur, when using this disposal method, the substance enters the atmosphere and, when interacting with water, sulfuric acid is formed.
4. Recovery is a process similar to recycling. This is the most promising and rational way. So, in the manufacture of one new tire, approximately 30 liters of crude oil are consumed, and only 5 are needed for restoration.

In recent years, business in this area has been gaining momentum, it is especially popular in European countries, since it is there that society takes environmental protection most seriously.

Another clear advantage that this business is famous for is the purchase of inexpensive equipment for processing tires into crumbs. You can organize a recycling plant with your own hands in any room, even in your own garage.

Tire crumb line

The tire recycling line produces crumb rubber for business, it is considered environmentally friendly due to the absence of emissions into the atmosphere or into the ground.

The line and all equipment must be made in accordance with the requirements of the Russian Federation, which were put forward for equipment of this type:

• The level of noise emitted.
• By the amount of harmful emissions.
• According to life safety.
• Accordingly, the safety of waste processing.

The whole line for processing tires into crumbs consists of sectors:

• Preparatory, which includes 2 machines: 1 - for removing bead wire, 2 - shears for cutting tires.
• Crusher, consisting of 1 - crushing chamber and 2 - return sifter.
• Crushing rollers, representing two drums that rotate at different speeds towards each other.
• Granulator that feeds the mixture from the feed funnel to the crushing zone.
• Vibrating table of a magnetic selector for uniform distribution of the mixture under the influence of vibration.
• Knife granulator, consisting of a body with knives, a shaft with knives, a mesh with a hole diameter of 4 mm.
• Vibrating table in the form of an inclined rectangular structure.
• Magnet for picking up fine wire residues.
• Textile separators for a high level of crumb removal from textiles present.
• Automatic packers filling bags with crumbs.

This is how the process of recycling tires into crumbs, which serves as a secondary raw material for further production, looks like. It is not difficult to organize this recycling business. This is due to the relative cheapness of equipment and fast payback periods. The main mission of this business is to protect the environment.

Recycling old tires at home

Recycling tires into crumbs at home and at the factory

It should be noted that this rubber waste is a flammable material, and if a huge number of tires ignite, they can pose a threat of poisoning to everyone nearby, since rubber, when burned, releases carcinogenic toxins, such as benzpyrene. Storage in landfills leads to the reproduction of rodents and insects, which are sources of dangerous infections. To avoid the deterioration of the environmental situation in Russia and abroad, proper disposal is required, namely, waste processing.

Without constant recycling, an environmental crisis could set in very soon.

Recycling

Powder from waste of larger fractions is used in the production of composite roofing materials, rubber-bitumen mastic, waterproofing materials, and rubber coatings. Scrap metal is obtained from a metal cord, which is also used by Russian entrepreneurs.

Also, textiles and rubber are obtained from tires.

Recycling at home

According to one of the scenarios, the rubber should be cooled to a temperature of approximately -75 ° C. Agree, not everyone has such an opportunity. So let's use the traditional scenario:

• Take the cameras
• Remove all unnecessary elements from them
• Cut them into thin strips
• Grind those stripes

The rubber grinder in this case is an ax or scissors.

Mechanical processing method

The most professional way.

The technological line is a sequence of installed working devices, overcoming which the material becomes a finished product.

Processing into crumb rubber goes through three stages:

Today, there are a sufficient number of manufacturers of this equipment on the Russian market.

Chemical processing method

There is also an effective, but expensive physico-chemical method of processing tires into crumb rubber - cryogenic grinding of car tires. Crushing of rubber is carried out in a special cooling chamber at extremely low temperatures (up to - 120 ° C). A refrigerant (liquid nitrogen) is supplied to this chamber, cooling to ultra-low temperatures.

In conditions of strong cooling, the rubber acquires a glassy state. Crushing of rubber occurs when struck with a special hammer.

After grinding, textiles and metal are removed from crumb rubber.

Recycling of automobile tires to obtain crumb rubber is carried out in several stages: Note that the processing of rubber can be both crumb and diesel fuel. But the latter option requires serious material investments. This process consists of sorting and subsequent grinding of tires, and then the selected and prepared material is loaded into a special reactor, which extracts fuel from recycled materials at high temperatures.

Utilization and recycling of car tires

Let's see what can be obtained as a result of recycling old tires: crumb rubber, which is used in the production of various gaskets and seals (including for sanitary purposes), shoe soles, rubber mats, rubber roofing (you can learn about liquid rubber for roofing here) , Novotek seamless coatings, as an additive in asphalt, a filler for punching bags, and for many other purposes.

Business Idea: Tire Recycling

Its waste is released into the environment.

This is not a good solution, but the emission resembles the exhaust gases of a truck.

As for the remaining mass, it passes through a magnetic separator, in simple words, it is sifted through a sieve. Metal elements are screened out and sent to the warehouse.

Fuel oil is transported by a conveyor to tanks, in which the fuel will be stored until shipment.

Tire recycling: step-by-step opening of production

Therefore, the choice is obvious: it is better to recycle used tires and get paid for it than just burn them, causing harm to the environment.

Based on the chosen method of tire recycling, different products can be obtained: Let us consider the process of tire recycling using the example of crumb rubber production, which has a wide range of applications. So, the process consists of the following steps: In the future, the resulting crumb can be converted into fuel / gas / fuel oil.
