Abstract

An apparatus (1) for reducing various material to smaller sizes emphasizing large volume with long pieces. The apparatus has a frame case, with an infeed (43) and outfeed, within which at least one rotor (4) with at least one radially tilted forward cutter bar (16) cuts the material against one anvil (22). A grate (29, 32) is used to size the material to final product dimensions. The frame case is angularly split. Where more than one rotor is used, they are radially offset.
