If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.

Obviously, the SAG mill is consuming more and the ball mill less power than was predicted by the empirical method, but the overall total is 99.5% of the predicted total. Examples. The Hemlo gold project of Teck-Corona (1000 mtpd) provides an example of mill sizing using the empirical calculation method alone.

These mills typically grind ROM ore in a single stage. A large example of such a mill was converted from a single-stage milling application to a semi autogenous ball-mill-crushing circuit, and the application is well described. This refers to high-aspect AG/SAG mills. Ball Charge Motion inside a SAG Mill. With a higher density mill charge.

1. Cylindrical Shell: The ball mill consists of a hollow cylindrical shell that rotates about its axis. The shell is usually made of steel, stainless steel, or rubber. 2. Liners: An abrasion-resistant material such as manganese steel or rubber typically lines the inner surface of the cylindrical shell to protect it from wear due to the grinding action.

The ratio of active mill shell surface area to ball charge surface area for the 5.0 meter (16½ foot) unit, is roughly half of that for the 2.4 meter (8 foot) unit. However, the actual ratios are so small (1 or 2 percent) that the amount of grinding at the shell is likely of little significance for either size.
