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.

The other major repairs that take place on ball mills are to replace the liners and diaphragms and on a VRM to replace (or turn) the rollers and replace the table. The liners on a ball mill generally last up to 5 years in the first chamber and as long as 8 years in the second chamber and therefore are infrequently changed.
