ABSTRACT:
A rubber reduction and recycling system with dramatically reduced power requirements. The present invention provides a series of reduction stations which successively reduce the size of the rubber, typically in the form of tires, to eventually result in crumb rubber. The power requirements are dramatically reduced by providing a fixed cutting plate through which the teeth of the cutting apparatus pass and cut the rubber in a shearing fashion. Moreover, the teeth of the cutting apparatus pass through the fixed cutting plate at an angular disposition so that at any given point, a relatively small portion of the rubber is being cut and thereby consuming power. Finally, the power consumption is reduced by providing the teeth on rotating shafts in a plurality of series of arcuate patterns. Therefore, at any given time, only a relatively small number of teeth in each series cut at the same time and thereby require power.
