Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation a portion of the charge is lifted along the inside perimeter.

SAG mills have a power higher than 10 MW. Even ball mills have a power larger than 10 MW. For this reason they have an important impact in energy consumption and in the operation of the power distribution system. Figure 1. Picture of a typical GMD system for a SAG mill Figure 2 presents the power circuit of a cycloconverter fed synchronous motor.

Under given load and particle size requirement capacity is a function of mill length and diameter Q = kLD 2 N. N is related to mill diameter which decreases with larger diameters k a constant equal to π /4.
