The roller mill has a grinding roller (1, 2) which revolves in a grinding ring (3, 4), the diameter of the grinding roller corresponding to at the least the inside radius of the grinding ring. The grinding roller (1, 2) is kept in motion by a tangential force from a drive (7). To this end, the drive (7) drives a drive table (20) to which two parallel stop beams (21) are fastened. Projecting between these beams is a stop body (23) which transmits the force to the grinding roller. The grinding roller (1, 2) and the grinding ring (3, 4) are each suspended on three universal shafts (6 and 5 resp.) and can be deflected laterally. This arrangement ensures that the centre of gravity of the grinding roller always revolves in the grinding ring at a constant revolving frequency. In addition, the suspension of the grinding roller by universal joints guarantees that its rotary impulse does not change during the revolving so that the torques acting on the mill housing remain small. <IMAGE> |
