perfect for coal mills with a power range up to 1,500 kW. Both gear series meet the general requirement of vertical roller mill drives. With one bevel and one planetary gear stage our WPU Gear Unit reduces the speed of the electrical motor to the desired grinding table speed and changes the horizontal input axis into the vertical output axis.

The basic structure of the roller mill includes the grinding roller, the grinding body, the force generation and transmission mechanism, airflow, and the device for easy replacement. It can be divided into vertical roller mill, horizontal cylinder roller mill, high pressure roller mill, Raymond mill, and column mill.

A conventional drive train contains a horizontal electrical motor and gearbox. In addition to the torque increase, the gearbox also redirects the rotation movement from the horizontal direction into the vertical axis of the mill table utilizing a bevel gear stage. This bevel gear stage represents the limiting factor in torque transmission.
