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.

Critical speed is the rpm at which the media will be stuck to the side of the jar based on centripetal force. All of the values in the formula are to be used in inches. I'm not sure how the 265.45 value is derived, but it is based upon inches. Critical speed = 265.45 / sqrt (jar ID - media diameter) Optimal speed is 65% of the critical speed.

Ball milling is a mechanical process that involves the rotation of a drum containing grinding media, typically steel balls, at a high speed. The materials to be milled are loaded into the drum, and as the drum rotates, the grinding media collide with the materials, causing them to break down and reduce in size.

For example, using well established relationships between power draw and mill diameter and speed, 50 mm (2 inches) of liner wear results in about 14 percent power increase (at constant loading and rotational speed) for a 2.4 meter (8 foot) diameter mill, as opposed to only 6 percent for a 5.0 meter (16½ foot) diameter unit.
