The Ball-Mill Drive System Looking inside the mill& 39;s motor compartment you can now see the motor with a small fan and pulley on its shaft. That small pulley is connected by a drive belt to a large pulley which is mounted on the unit& 39;s drive roller.
The most economical drive to use up to 50 H. P. is a high starting torque motor connected to the pinion shaft by means of a flat or V-Rope drive. For larger size motors the wound rotor slip ring is recommended due to its low current requirement in starting up the ball mill.
These large coal crushing drive systems are usually rotated by motor-driven gearing. A typical appli ion consists of a motor-driven primary single-stage reducer that through a flexible coupling drives a large open pinion which in turn meshes with a large ball mill ring girth gear that is attached directly to the ball mill.

Nowadays more and more mills are fed by frequency converter systems allowing for higher performance and flexibility of operation. ABB continuously extends technical and performance frontiers of ring-geared mill drive RMD technology to fit your site requirements.
Ball Mill SPEED REDUCER DRIVE This is essentially a direct connected drive permitting the use of higher speed motors. The motor shaft is connected to the high speed shaft of a reducer by a flexible coupling and similarly the low speed shaft and pinion shaft are coupled.
