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