FIELD: rubber-processing industry.
SUBSTANCE: method of elastomer destruction includes preliminary grinding and phased destruction and homogenisation in single-screw disperser separated by process zones which are connected with transportation areas. Water is introduced into the first process zone in the amount of 2-15 mass.% from rubber weight. Rubber is destructed in the first zone under the pressure being decreased as long as material flows. Then, it is transported while material is re-circulated. Temperature in the first zone is maintained at a level of dissipation heating temperature not exceeding 250°C. Final destruction takes place in the second process zone at heating temperature not exceeding 300°C.
EFFECT: decrease of plasticity properties in produced regenerate.
