Every procedure used in the grinding tests is described in detail in Mazzinghy (2009). 4. Results. Ball charge sampling. The ball charge of the industrial ball mill was sampled during one of the maintenance stops. The mass of balls required to consider the sample representative was too high and it was not possible to achieve the necessary mass.

Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.

There are three commonly overlooked procedures that will affect production when maintaining a ball mill. It is a mistake to not include data collection, high ergonomics, and more powerful impact wrenches into maintenance procedures. The results can be costly and time-consuming.
