Abstract: A continuous pyrolysis system is adapted for continuous pyrolysis of tire shreds with the simultaneous recovery of solid, liquid, and gas pyrolysate. The pyrolysis system includes an anaerobic pyrolyzing chamber with a conveyor for conveying tire shreds therethrough from an infeed end to a solids output end, and a heater for pyrolyzing the tire shreds as they are conveyed. The system also includes a solid pyrolysate output device for removing solid pyrolysate from the chamber, a liquid and gas pyrolysate output device for removing liquid and gas pyrolysate from the chamber, and a tire shred infeed device for feeding tire shreds into the chamber without interrupting either the pyrolysis of tire shreds already in the chamber, or the removal of pyrolystate from the chamber.

Abstract: A tire shredder. A housing has a vertical passage therein leading to a series of transversely disposed cutter wheels on adjacent parallel shafts. The shafts are rotated at different speeds, such as at 28 r.p.m. for one shaft and 34 r.p.m. for the other. The cutter wheels have flat side walls that partially overlap, so that rotation results in a scissors action reducing the rubber tires into manageable and disposable pieces. Preferably each cutter wheel has at least one tooth for engaging tires and pulling them into the shredder.
