ABSTRACT:
A rotary shredder for shredding various materials including fibrous materials, comprising at least one rotor that carries a plurality of V-cutters axially spaced apart along the rotor to mesh with recesses between adjacent teeth of a counter knife. The rotor also carries a plurality of flat cutters. Each flat cutter has a cutting edge that is parallel to the axis of the rotor. The flat cutters are aligned in the axial direction with the teeth of the counter knife, and hence are axially positioned between axially adjacent V-cutters. The flat cutters thus are positioned to work in conjunction with the counter knife to cut material that accumulates between adjacent V-cutters.
