Reduction structure including a revolving rotor and stationary structure. The revolving rotor is notched to provide a series of cutter sockets that individually receive cutters, preferably hardened steel cutters. The cutters are arranged in their sockets such that a majority of the length thereof is disposed within each socket; thereby, bolt attachment means may be reduced in number and can conceivably be one in number per cutter. The ends of the shaft are preferably turned down for bearing support and coupling to adjacent prime mover structure. The hopper, within which the rotor as above-described is mounted, preferably includes an anti-rotation member in the form of an elongate bar having one or more declining flanges, these flanges serving to preclude counter-rotation of any element such as logs as may be introduced into such hopper. For reduction such as shearing in connection with automobile and truck tires, the clearances around the individual cutters as the same pass through notches within the stationary cutter bar employed should be reduced to not more than 1/8th of the cutter width; by this restriction the cords in tires are sharply cut and do not string out from cut segments so as to foul materials-handling machinery, screens, and so forth, as may subsequently be used.
