Ball Mill Crushing Mineral Processing Metallurgy Ball Mill Crushing by tubemills were first introduced into the crushing departments of cyanide plants when it was found that for crushing finer than 30mesh other types of crushing machinery were not efficient In order to crush with one pass these mills were made 18 to 22 ft 55 to 67 m in length Pebbles were used as a grinding medium and the mills were

Photographs of a glass ended laboratory ball mill show action of ball mass within the mill The action of other grinding media is similar The action of other grinding media is similar As the mill revolves lifters assist in picking up the grinding charge and elevate it to an angle at which gravity overcomes friction and centrifugal force
