For single pinion and dual pinion drives, with 21 MW now a distinct possibility, the probability of pinion changes to a higher mill speed should always be considered when set-ting gear ratios, service factors, and motor power ratings. For gearless drives, motor torque output at the maximum desired operating mill speed and ball charge volume has to

Flexible drive solutions for use in ball mills A ball mill is a horizontal cylinder filled with steel balls or the like. This cylinder rotates around its axis and transmits the rotating effect to the balls. The material fed through the mill is crushed by the impact and ground as a result of the friction between the balls.
