Abstract:
1. A comminuting device for material to be comminuted, the device comprising a driving device that drives at least one comminuting rotor having a rotor axis, the comminuting rotor presenting on the periphery thereof a plurality of comminuting tools that are fixed to said comminuting rotor, for forming a knife bank extending slantingly with respect to the axial direction of said comminuting rotor, the comminuting device further comprising at least one counterknife arrangement having a shape that corresponds to the rotation surface of the comminuting rotor so as to cooperate with said comminuting tools for disintegrating the material to be processed, wherein within the knife bank neighboring comminuting tools are arranged adjacent to each other and abutting on each other at respectively associated lateral faces, and a cutting edge of each tool is offset with respect to a cutting edge of each neighboring tool on the periphery of the rotor, wherein equivalent cutting edges of neighboring comminuting tools have the same distance to the rotor axis and each lie in a plane that runs parallel to the rotor axis.
