Abstract: The roller mill according to the invention is composed essentially of at least two grinding rollers which interact with a grinding plate for comminuting material to be ground, wherein the at least two grinding rollers or the grinding plate and at least one grinding roller are each assigned a separate drive train for driving same, wherein each drive train has a main motor and a main gear mechanism. At least one drive train additionally comprises a superimposition gear mechanism with a regulating drive, wherein an open-loop and closed-loop control device which is connected to the at least one regulating drive is provided, said open-loop and closed-loop control device regulating the power of the separate drive trains with respect to one another by means of the at least one regulating drive.

Abstract: 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.

Abstract: 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.

Abstract: The invention relates to a roller mill having a mill housing, a mill path which is supported so as to be rotatable about a mill axis inside the mill housing, and at least one mill roller which can be rotated about a mill roller shaft and which is engaged with the mill path in terms of rolling action. There is further provided a pivot lever which is for rotatably retaining the mill roller and which has a pivot shaft arranged parallel with the mill roller axis and which is supported outside the mill housing. The pivot lever is further in operational contact with a hydropneumatic resilient system in order to adjust the pressing pressure of the mill roller. The pivot lever is supported outside the mill housing with spacing therefrom in such a manner that the forces which are produced by the hydropneumatic resilient system are dissipated into the mill foundation directly or via pillars.
