Cryogenic grinding represents an opportunity for expanding recycling capabilities to a broad range of compounds. Many materials that can be reduced to a powder by conventional coarse grinding can be reduced more efficiently by using a super-cold agent such as liquid nitrogen at -320/sup 0/F to embrittle plastic or rubber polymers before grinding. In addition, cryogenic grinding makes possible the size reduction of many materials that cannot be ground by conventional ambient grinding methods. Some experiences of cryogenic grinding in practice at United Tire and Rubber company, Limited, headquartered in Rexdale, Ontario, are noted. A schematic of such a system is shown.
