ABSTRACT:
A machine for reducing worn-out vehicle tires to small chip-like particles comprises a frame on which an elongated shaft is journaled for rotation, the shaft having a first and second plurality of rotary cutting blades, each of a different diameter affixed to the shaft so as to be rotatable therewith. Also affixed to the frame is a set of stationary cutter bars whose sharpened edges are disposed within a predetermined close tolerance to the periphery of the rotary cutting blades. A large, massive flywheel is attached to one end of the shaft and is driven by a suitable motor. Surrounding the rotary cutting blades is a shroud which, in turn, suppots an infeed hopper having a spiked drum journaled therein. A chain and sprocket combination couples the infeed drum to the elongated shaft such that when the shaft is driven and relatively large chunks of vehicle tire material is placed into the infeed hopper, it will be forced between the teeth of the rotary cutting blades and hence carried by the rotary cutter through the stationary cutter bars.
