Load Sharing of Dual Motor Grinding Mill Drives
Relatively small slowly varying shaft position and velocity variations superimposed on the normal running speed of dual drive grinding mill motors can cause individual motor torque variations which disturb load sharing. The magnitude of load or torque unbalance is a function of the magnitude of the mechanical variation, the type of motors used, i.e., …

Solids | Choose the Right Grinding Mill
There are many different types of grinding mills (Table 1). Some devices, such as ball mills, are more suitable for coarse materials. These mills use "large" media, ranging in size from 20 mm in diameter and up, to produce material from about ten microns to mesh sizes. Attrition mills are more appropriate for "mid-range" size particles.
