Abstract
A process, and associated apparatus, that separates the economic components of scrapped rubber tires while isolating and removing certain levels of contamination associated with these tires. The separation of the scrap tires contaminants is accomplished by shredding, washing, and rasping the tire product. The continual laboratory testing of the waste wash water and removal of the contaminates and particulates will produce an end-product of 3 to 100 mesh/crumb which will be virtually without contamination. The quality of the end-product is further enhanced by the associated quality apparatus that removes the steel and fiber products in addition to any contaminants.
