A roller mill includes a grinding table, at least one grinding roller in rolling engagement with the grinding table, a main drive system for driving the grinding roller and/or the grinding table, and an auxiliary drive for driving the grinding table. The auxiliary drive includes at least two linear drives for rotating the grinding table and a control device for individually controlling the linear drives in order to provide an uninterrupted rotational movement.

Roller mill and method for driving a roller mill

A roller mill includes a rotatable grinding table, at least one grinding roller that is retained rotatably on a pivot lever and is in rolling engagement with the grinding table, with the pivot lever being arranged for pivoting about a pivot lever axis, and a drive train associated with the grinding roller in order to drive the grinding roller with a fixed motor.

Roller mill with driven grinding roller

A roller mill includes a mill housing which defines a grinding chamber, a grinding table which can rotate in the grinding chamber and at least one rotatable grinding roller which is in rolling engagement with the grinding table. A drive which is associated with the grinding roller and which has at least one gearing mechanism is further provided, at least a portion of the gearing mechanism being arranged in the grinding chamber in the region of the grinding roller and being in the form of an epicyclic gear system.

A roller mill includes a rotatable grinding table, at least one grinding roller retained rotatably on a pivot lever and in rolling engagement with the grinding table, the pivot lever being pivotable about a pivot lever axis, and at least one drive train connected to the grinding roller and having a fixed motor and a fixed gearing mechanism. The drive train further has a gearing mechanism which pivots with the pivot lever and/or the grinding roller.

Roller with driven grinding roller

The roller mill according to the invention substantially comprises at least one grinding roller and a grinding table, the grinding table having a grinding table inner space which is open in a downward direction, at least one grinding roller drive system for driving the grinding roller and a grinding table drive system for driving the grinding table. The grinding table drive system further has a gearless direct drive which is arranged in the grinding table inner space.

Roller mill

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.
