ABSTRACT:
The invention relates to process for recycling tires and other recyclable materials. The process includes a series of steps designed to reduce a rubber or polymer tire into pulverized material. The process involves first shredding the tires or recyclable material into chips. The chips are then cooled to cryogenic temperatures at which said pieces become brittle. The brittle pieces are then pulverized in the second step. Pulverized material is then screened, removing large chunks of rubber or polymer from the mixture. Finally, the remaining fiber and magnetic material is separated out of the pulverized material, through the use of a magnetic separator and a vibrational (fiber) separator.
