The ozone method of rubber destruction can be considered to be a promising technique, in which the energy consumption per 1 kg of obtained crumb rubber does not exceed 0.02 kW per hour. The ultimate use is mixed with bitumen to obtain rubber asphalt. Because the simple act of destruction on the rollers is due to the creation of ultimate stresses in the particles of the crushed material, which arise due to the difference in the speeds of rotation of the rollers, it has been found that an increase in roll friction leads to an increase in productivity. The use of reclaimed rubber in the production of elastomeric materials and products saves rubber, carbon black, and softeners. A well-known method allows for the reduction of energy consumption during crushing by impact. Due to the continuity, speed, complete mechanization, and significant automation of the devulcanization process, this method of obtaining reclaimed rubber is the most technologically advanced as compared with other applied methods of rubber reclamation.
