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, through the gearbox, into the mill foundation.

Which component parameters of the vertical roller mill have

According to the working principle of the vertical roller mill, when the speed of the separator is constant, the wind speed of the feed port is larger, and the fineness of the finished material is lower. An increase in the speed of the separator causes the disc to generate more centrifugal force, resulting in a finer material. The control of the separator speed is the main method for manual adjustment of material fineness.
