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 grinding process in AG mills is unique compared to other types of mills, as it is an autogenous process. This means that the ore itself is used to grind and crush itself, rather than relying on external forces like the steel balls or rods in traditional grinding mills. The ore is fed into the mill along with water, and as the mill rotates ...
