ABSTRACT:
A comminutor for comminuting solid materials carried by flowing fluids, such as industrial wastes or sewage, in which cutter elements carried by a plurality of rotating rings forming a cone shaped rotor co-act with stationary cutter elements supported alongside the rotor, and a method of comminuting. The stationary cutter elements are reversable so that upon repositioning, new stationary cutting edges are presented to the cutter elements carried by the rotating rings. A plurality of stationary cutter elements are formed on a single structure, each stationary cutter element forming a cutting station. The cutting action is further increased by providing co-acting cutting edges in planes perpendicular as well as parallel to the rotor axis at each cutting station.
