摘要：Scrap tires containing magnetic components and non-magnetic rubber and cord components are cooled in a cryogenic freezer to the embrittlement temperature, comminuted in a comminution device and passed through a series of screening and density classification operations followed by magnetic material separation and further cryogenic size reduction to produce a product rubber crumb having a particle size of about 1/20 inch or less.
