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 speed and to transmit the torque created by the motor. Secondly, the gearbox has to transmit the grinding forces generated by the grinding rollers, from the mill table

Roller mill Wikipedia

Roller mills are mills that use cylindrical rollers, either in opposing pairs or against flat plates, to crush or grind various materials, such as grain, ore, gravel, plastic, and others.Roller grain mills are an alternative to traditional millstone arrangements in gristmills.Roller mills for rock complement other types of mills, such as ball mills and hammermills, in such industries as the

High-power drive system for vertical roller mills

The oil supply units for our vertical roller mill gear units and drive systems includes low-pressure pumps to feed bearings and toothings with filtered and cooled lubrication oil. If required, high-pressure pumps supply the oil for the thrust bearing from a separated compartment of the tank filled with filtered oil from the low-pressure part.

how to improve grinding efficiency of vertical roller mill

The differential pressure of the vertical roller mill is generally controlled at 5000~7000Pa to ensure the proper air volume. The change of the pressure difference within the mill is mainly affected by the feed amount when other conditions are constant. Therefore, the feed amount should be stabilized.
