ABSTRACT:
A rotor shear for comminuting particularly bulky waste materials is formed by two cutting rotors (2) combing each other, disposed parallel to each other, supported in a housing (1), and each driven in an opposite direction. Each cutting rotor (2) comprises spacer rings (4) and rotor disks (5) furnished with cutting teeth (6). A face of a front flank (61) of at least one cutting tooth (6) is furnished with geometrically staggered and/or angled partial faces (65). The spacer rings (4) and the rotor disks (5) are disposed on shafts (3). Wear disks (7) are coordinated to outer rotor disks (5) with corresponding circumferences and are connected to the shaft (3). The cutting teeth (6) operate against the circumference of the spacer rings (4) disposed between the rotor disks (5). At least one support device/stripper device (8) is coordinated with at least one shaft (3), where support parts (81) and stripper parts (82) of the support device/stripper device (8) are functionally separated.
