Abstract

A material reducing machine includes a rotor assembly having a plurality of short cutting tools and a plurality of long cutting tools. The short cutting tools are arranged in rows which extend across the length of the rotor assembly, which rows are spaced around the periphery of the rotor assembly. The long cutting tools are also arranged in rows which extend across the length of the rotor assembly, which rows are spaced around the periphery of the rotor assembly. Each of the long cutting tools has a cutting bit with a leading edge that is spaced outwardly from the periphery of the rotor assembly by a long cutter distance that is greater than a short cutter distance of each of the short cutting tools. A breaker assembly includes a plurality of shear blocks, each of which is spaced so as to be aligned with a short cutting tool.
