ABSTRACT:
A system for treating rubber tires which reduces the tires to a particulate agglomeration wherein cord and rubber matter therein can be separated. A further treating of those rubber particles reduces them to screen size. The system requires the steps of: (a) initially debeading the tire; (b) cutting the tire into chunks; (c) regulating the quantity of chunks as they pass through the system; (d) grinding the tire in a high intensity mixer; (e) passing the grind to a hammer mill to loosen the rubber and the cord from one another; (f) separating the rubber particles out in a separator, and (g) then grinding the rubber particles to a size of about 30 to 100 mesh as a final product. Oversized pieces of rubber discharged from the separator near the end of the system would be returned to the high intensity mixer.
