  • Patent number: 7552883
    Abstract: The invention relates to a crushing device, which includes a frame structure and a rotor mounted rotatably in bearings in it. In addition, shredder elements are arranged in connection with the frame structure and the rotor, and a hydraulic motor is connected to the rotor through a power transmission. The material fed to the crushing device is arranged to travel through the shredder elements while at the same time being crushed into smaller pieces when the rotor is rotated by the hydraulic motor. At at least one end of the rotor, the rotor is fitted to the frame structure by means of a pivot joint, which permits a difference of angle between the rotor and the frame structure.

  • Publication number: 20070257145
    Abstract: 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.
