Portable apparatus for shredding waste materials, particularly reinforced resilient materials such as used pneumatic tire casings, in which generally cylindrical cutter rolls, each comprising a plurality of cutter discs, are intermeshed with one another to shear scrap material into smaller pieces, and feeder-stripper rolls, each comprising a plurality of feeder-stripper discs, are intermeshed with the cutter rolls but spaced apart from one another. The cutter rolls are rotated in opposite directions, and each feeder-stripper roll is rotated in the same direction as the cutter roll with which it is intermeshed, thereby feeding scrap material between the two feeder-stripper rolls toward the cutter rolls. The feeder-stripper discs extend deeply between the cutter discs to eliminate clogging. The feeder-stripper rolls may be movable to provide greater separation for receiving and feeding larger pieces of scrap material into the casting mechanism. A conveyor is pivotable with respect to the shredding mechanism to carry shredded material to any of several positions relative to the apparatus.
