Crushing machine for breaking down quasi-homogeneous material e.g. briquet, has synchronous motor that is excited by frequency controllable feeding unit, where synchronous motor operates over trivet drive on rotor

摘要

The machine has a rotor (14) that carries a cutter body (16, 18). A counter blade arrangement is attached to a frame, where the counter blade arrangement cooperates with the cutter body of the rotor. A synchronous motor (46) is provided and is excited by a frequency controllable feeding unit. The synchronous motor operates over a trivet drive (48) on the rotor, where the trivet drive comprises a chain drive.
