Abstract
In a method and apparatus for comminuting waste to minimise the risk of damage to the apparatus and to provide quick flexible reaction to changing operating conditions the comminuting apparatus includes a drive unit having at least one electric motor in the form of a between 12-pole and 32-pole three-phase synchronous motor operating at a rotary speed of between 1 and 500 rpm. The motor is electrically connected to the output of a frequency converter controlled by a control device. The drive shaft of the motor is connected without interposed transmission directly to the comminuting shaft and no torque- and/or force-transmitting drive element rotates more quickly than the drive shaft of the motor.
