Abstract
A roller mill includes a grinding table arranged for rotation about a mill axis, at least one grinding roller rotated about a grinding roller axis and in rolling engagement with the grinding table, and at least one pivot lever retaining the grinding roller and having a pivot axis orientated parallel with or inclined relative to the grinding roller axis. A fixed motor is connected to the grinding roller via a drive train to transmit drive power, the drive train including a fixed drive train and a movable drive train. The fixed drive train has a drive element in contact with the movable drive train and arranged coaxially relative to the pivot axis of the pivot lever. The two drive trains may be connected to each other via two bevel wheels arranged so that the axes of the bevel wheels intersect in the pivot axis.
