ABSTRACT:
A ball mill with a housing (1) that accommodates three stationary rollers (2) rolling along a rotating track (3). The rollers are held against the track by means of an upper and lower frame (9 & 10). The frames have springs (11) between them. Rods (8), each connected to a hydraulic cylinder (24) and extending out of the housing, engage the upper frame (9). To allow the rollers to be lifted off the track, a piston associated with the hydraulic cylinder can be charged at either end, the rollers are attached to the lower frame with hinges 25 and an angle-setting device, and the frames are connected by tension structures that limit the expansion of the springs.
