Embodiment Construction

[0018] The roller mill shown in the figures generally comprises: a rotatable grinding table 1; at least one grinding roller 3, which is rotatably held on a pivot rod 2; and a transmission system, which is connected to the The grinding rollers are associated so as to be driven by a stationary motor 4 . The pivot lever is arranged in a bearing 5 so as to rotate about a pivot lever axis 6, one end of which is outside the mill frame 7, while the grinding roller 3 is held on the pivot lever axis 6. The end of the rotary rod is located inside the mill frame.

[0019] A pressing system 8 , in particular a hydropneumatic elastic system 8 , is also provided in order to adjust the pressing pressure of the grinding roller 3 . The pressing system is also arranged outside the mill frame 7 and is in working contact with the pivot lever.

[0020] The grinding roller 3 is arranged to rotate on the pivot lever 2 via a grinding roller bearing 9 . The pivot lever 2 can furthermore be in the f...

Abstract

The roller mill according to the invention substantially comprises 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.

Description

technical field [0001] The invention relates to a roller mill having a grinding table rotatable in a grinding chamber, at least one grinding roller in rolling engagement with the grinding table and at least one transmission system associated with the grinding roller. Background technique [0002] Roller mills are used in industry, where a driven grinding table typically drives the rollers through the grinder. In this case, it is usually necessary to provide a gear mechanism under the grinding table. In high-volume grinding mills, high investment costs, long procurement times and unsatisfactory availability of the gear units have to be taken into account. [0003] Therefore, it has been proposed to drive the grinding roller instead of the grinding table. If multiple grinding rollers are provided, it is possible to distribute the power for driving the roller mill to corresponding multiple drives. In this way it is possible to use smaller and thus cheaper drives. [0004] I...
