摘要

The invention relates to a crushing device, which includes a frame structure (10) and a rotor (13) mounted rotatably by bearings at its ends to the frame structure, shredder elements (14, 15), which are arranged in connection with both the frame structure (10) and the rotor (13), at at least one end, a hub motor (19) connected to the rotor (13) through a planet gearbox. As a continuation of the rotor at the hub-motor (19) end, there is an extension piece (30) , inside which the hub motor is arranged to fit in terms of its length too. The rotor (13) is arranged to be detachable/attachable at its ends over the length of the above or below trough (8, 9) and can be changed through this trough (8, 9) .
