A comminuting apparatus having a compact, variable-speed drive unit with a high level of efficiency and high torque levels. The comminuting apparatus comprises a drive device having an electric motor operatively connected by way of a transmission device to a comminuting shaft that has comminuting tools at its periphery. The tools cooperate with a counterpart member to comminute the material to be processed. The electric motor is in the form of a high-pole three-phase synchronous motor that is electrically connected to the output of a frequency converter controlled by a control device, and the transmission device is in the form of an epicyclic transmission device. The motor surrounds the epicyclic transmission device at least in part, and the motor and the transmission device are arranged in a common housing.
