Construction of Ball Mill: The basic parts of the ball mill are a shell, balls, and motor Fig.2. A ball mill is also known as a pebble mill or tumbling mill. It consists of a hollow cylindrical shell (drum) containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis. The axis of the shell may be either ...
advanced process control to provide maximum mill control. It can be applied to new or existing semi-autogenous (SAG), autogenous (AG) and ball mills, powered by either ring-geared mill drive systems (RMD) or gearless mill drive systems (GMD). SmartMill™ is designed to control, stabilize and optimize mill operation.

general, the bigger the mill diameter, the lower are the mill operating and critical speeds. Thus, for larger mills the number of poles will increase. As a result, the number of poles can vary from 48 to 72 poles (Fig. 3.) with typical mill speed requirements of about 10 rpm for larger SAG mills and about 15 rpm for smaller ball mills. Figure 3.
