Material shredding apparatus for reducing scrap vehicle tires to produce two sub-products of rubber and of rubber free steel wire in which the apparatus has a shaft driven set of blocks in which each block has cutting teeth in circumferentially spaced relation, the respective blocks are keyed to the shaft so the cutting teeth on the blocks are circumferentially distributed along the shaft at 15.degree. spacing to assure that the cutting teeth perform a cutting function one at a time to avoid excessive power consumption and the material being shredded is distributed along the set of blocks on the shaft to reduce local areas of wear.

Material shredding apparatus

Material reducing apparatus having a drive arrangement for a pair of shafts carrying double edge cutter discs, motor driven transmissions for each shaft having different speed characteristics for reducing motor speeds to double digit speeds, bearings mounted in pillow blocks so that the pillow blocks can be opened to allow removal of the bearings so the shafts carrying the double edge cutters can be repositioned to present the cutters selectively to reduce material with either edge of the double edge cutters. The drive arrangement is also duplicated at the opposite ends of the pair of shafts for selective connection to drive the shafts either by one of the drive arrangements or by the duplicate drive arrangement.
