Drive Systems for Vertical Roller Mills IEEE Xplore

Because of simple scalability and low energy consumption, the vertical roller mill is a key part for single mill cement lines. The limits of material throughput of VRMs are, unlike other mill types, not defined by the comminution process itself but by the transmissible torque of the drive train. Therefore the size of conventional
