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.
