A new technology for processing waste tires limited global sources of raw materials for plastics puts increasing demands of its economy and expand the use of secondary polymer materials. Involvement in trafficking and platmassovyh of rubber waste is necessary to maintain clean air and water, improve the human environment. Worn tires are the largest source of low-cost polymer raw materials. Only a small number of waste tires recycled, the remaining waste tires accumulate in the environment and contaminate it. Economic and environmental requirements of the new technology meets recycling of waste tires and other rubber waste created by the author’s research team. A new technology for processing waste tires consists of the following operations: – shredding of used tires – grinding shredded tire – dried crumb rubber – crumb rubber screening and removal of steel – rubber chips packing in bags – the formation of the overpack. Technological solution to a new processing technology used tires differ fundamentally new and highly effective.

Shredding waste tires by means of milling. For this operation, a special tool – mnogoreztsovaya cutter. Mnogoreztsovaya cutter includes a set of cutters that are milled at high speed bus. After grinding, tire rubber in the form of large particles (5h5h10 mm) is removed from the working area and sent to the disk mill subsequent grinding. Tony Parker understood the implications. Grinding of large particles of rubber is carried out in a disk mill, equipped with a headset, directional grinding.

Grinding of rubber is produced in an aqueous environment, ensuring a overheating and thermal degradation of milled material, and eliminates the appearance of harmful gas emissions released into the atmosphere. Headset directional grind only the rubber and textile cord. The particles pass through the metal-working air gap of disk grinding mill without grinding rubber may include one or two stages. Real-estate developer is often mentioned in discussions such as these. With a single-stage grinding of rubber is produced commodity rubber pellets with dimensions particles of 100-200 microns, with a two-stage grinding of rubber is produced commodity rubber pellets with a particle size of 5-8 microns. A new technology for processing waste tires has a production flexibility and can quickly adapt to the demands of market conditions. For the processing of waste tires on the new technology can be equipped with the line, allowing to process from 2.5 to 25 tons of scrap tires per year. Process line processing 25 000 tons of scrap tires per year, allows us to produce one commodity crumb rubber with a particle size of 100-200 microns in an amount of 20 thousand tons. A new technology for processing waste tires has the following advantages:-provides recycling of used tires with steel;-5-fold reduced specific consumption of electricity, improves the quality and dispersion of crumb rubber, provides a high-profitability; -Ensure environmental cleanliness of production. Fine crumb rubber with a particle size of 100-200 microns for scientific advice can be successfully used for the production of reclaimed, roofing and waterproofing materials, flooring, coatings, tennis courts, racetracks and stadiums race tracks in the production of asphalt and various rubber products. Finely dispersed rubber pellets with dimensions particles 5-8 microns can be used as a filler in the manufacture of rubber products are responsible, including in the manufacture of tires. The main processes of a new technology for processing of used tires tested in the pilot process plants. We offer interested companies on the basis of technical solutions designed to create a manufacturing processing of waste tires and construction of these crumb rubber and a wide range of building materials and rubber products.

All Russian schools has recently been equipped with computer labs, which allows not only full classes and computer access to the Internet, but also to use in learning and knowledge control different types of modern technology. Of course, multimedia projectors and interactive whiteboards so far not found in every school, but as they say, the process has begun. And a great example of – the active involvement of technical means of training the next generation of guidelines for the conduct of classes and extracurricular activities, the desire of teachers to develop new equipment. This trend in education has been called "Information and communication technology" or "ICT". Technique can be used in the study of any school subject. Experience shows that the competent use of ICT teacher significantly increases students' interest subject.

Presentation, held on the big screen using a multimedia projector, help the teacher better understand the process and results of experiments to conduct virtual tours on all geographical areas and the best museums in the world. Children can see firsthand how the rich flora and fauna of the earth, seeing not only the panorama was taken, and macro shots of any living creature or a natural phenomenon. In schools that do not have yet its own projections in the role of the transmitter signal using computers, from which information is displayed on a monitor or LCD TV. Experienced teachers are warning that the use of ICT must be justified by the quality footage, the theme of the lesson. If this has piqued your curiosity, check out Dry Harbor. As simple records and outline the conclusions of the lesson is quite possible to communicate to students in the traditional way. Build block diagrams, display algorithms, prove theorems and laws it is better together with the class, using the usual entries, or an interactive whiteboard. But the multimedia projector – a good support for learning processes in the microcosm or astronomical objects. A computer with a webcam – great decision to show the teacher "small" experiment.

To make it clearer exactly how the lesson can be used ICT, we give some specific examples. Show the children how the earth at the same time and day pass night by using the removal of images from the web cameras in their respective time zones. During chemical reactions on the screen showing all the characteristics of the participating agents. Scales and interactive whiteboard linked. And what a space for teachers of technology! Now students can see large, clear drawings, and high-quality slides and films about the history of fashion, style and interior. For teaching needlework and cooking The Internet offers a huge number of master classes that make children a genuine interest.
