Vertical roller mills (VRM) have dominated raw (VFC) for the motor. The VFC allows the mill speed to be continuously adjusted, ideally matching the specific grinding re-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.Drive systems for vertical roller mills IEEE Conference Publication
