FIELD: rubber.
SUBSTANCE: invention relates to production and use of reclaimed rubber of cured rubber crumb, such as rubber from wastes. Regeneration method involves stages of increased speed of rotor shaft to raise temperature of mixture, consisting of cured rubber crumb and lubricating material to devulcanization temperature; reduced temperature of mixture to lower temperature during second period of time. Device contains thermo kinetic mixer including airtight stationary chamber with relief inner surface.
EFFECT: invention improves environmental safety, reduced processing time, which eliminates risk of decomposition and self-ignition of rubber, reduces power consumption.
