1 A background to drives of vertical roller mills The drive of a vertical roller mill – essentially the mill gearbox – has to fulfill two tasks: The first is to reduce the speed of the electric motor to the selected mill .
Summary: The main trends concerning grinding processes in the cement industry are still higher efficiency, reduction of the power consumption and system simplicity. In the case of new orders, vertical mills have increased their share to over 60 % and ball mills have fallen to less than 30 %. It is somewhat surprising that the number of different grinding processes and mill types used by the ...

Roller Mils are directly driven bevelwheel planetary gears or bevel cylindrical gear units. The gear unit represents an almost integral component of the mill. The output flange of the gear unit is rigidly connected with the grinding table. In addition to transmitting the torque,the gear unit also has capability to take up the reaction forces from the the griding force of the mils rollers.
