Mill drives: the desire for increased power and the
design mill speed, and the maximum design ball charge volume (Barratt, 1989). 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.

TECHNICAL How to Spec a Mill Gear
Autogenous mills are the largest in diameter since the feed grinds itself. A semi-autogenous mill uses some metallic or ceramic balls to assist the grinding process and can be slightly smaller. Ball mills are smaller still and use a larger percentage of balls to perform most of the work. Large-di-ameter mills allow for use of gear ratios
