Roller Mils are directly driven bevel-wheel planetary gears or bevel cylindrical gear units. The gear unit represents an almost integral component of the mill. The output flange of the gear unit is rigidly connected with the grinding table. In addition to transmitting the torque,the gear unit also has capability to take up the reaction forces from the the griding force of the mils rollers.

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 .
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.
Gearbox for Mill This gear reducer is most suitable for driving a cement raw mill a clinker mill, a coal mill, and a slag mill, etc.. We are one of the world's leading companies for a gear reducer of a mill and have supplied more than 500 sets to world's customers which are highly evaluated.
The first gearbox generation for vertical roller mills consisted of two helical gear stages combined with a bevel stage as shown in Fig. 3. This concept was used from 50 kW up to 3900 kW. Today, this concept is normally used up to a power of approx. 1000 kW, while larger gearboxes are usually designed with a
situations in that, not only does a mill operate at generally lower vibration levels under LM-Master control – reducing wear on gearboxes and other major components – but the continuous monitoring of the mill process allows for Loesche is launching its new LM-Master for advanced vertical roller mill .
