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 times the drum diameter. Ball mills with a drum length to diameter ratio greater than are referred to as tube mills.

The method of ball distribution for a ball mill can be summarized as follows: 1. Take all the ore samples from a ball mill (usually take new ore and returned sand samples, then match the samples in proportion) for sieving analysis. Divide them into several particle sizes, such as 1812, 1210, 108, 86, etc. Then weigh each particle size, and ...
