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.

Roller mill comprising:
- a. a grinding table which is arranged for rotation about a mill axis,
- b. at least one grinding roller which can be rotated about a grinding roller axis and which is in rolling engagement with the grinding table,
- c. at least one pivot lever which is for retaining the grinding roller and which has a pivot axis, the pivot axis being oriented parallel with or inclined relative to the grinding roller axis,
- d. and having at least one motor which is arranged in a fixed manner for driving the roller mill, characterised in that the motor which is arranged in a fixed manner is connected to the grinding roller via a drive train in order to transmit the drive power, the drive train comprising a drive train which is fixed in position and a drive train which is also movable with the pivot lever and the fixed drive train having a drive element which is in contact with the movable drive train and which is arranged coaxially relative to the pivot axis of the pivot lever.
