Abstract

A comminuting apparatus for waster and/or production residues includes a drive device having at least one high-pole three-phase synchronous motor that is operatively connected to a comminuting shaft having at least one shaft bearing arrangement. The motor is connected directly to the comminuting shaft and the comminuting shaft over its working region has comminuting tools that cooperate with a counterpart member for comminuting the material to be processed. The comminuting shaft extends axially into the three-phase synchronous motor and the at least one shaft bearing arrangement of the comminuting shaft is surrounded at least in portion-wise manner by the synchronous motor.
