Ball Milling

Dry ball milling is a size reduction technique that uses media in a rotating cylinder to reduce materials to a fine powder. We have been milling various products for many years and have built a reputation for contaminationfree size reduction. We also pride ourselves in listening to the customer and adapting our techniques to suit their particular needs. We have been so successful in this ...

Conical Ball Mills differ in mill body construction, which is composed of two cones and a short cylindrical part loed between them ... The value of the comminution index, W, is also a function of R f. The finer the cement, the lower R f and the greater the maximum power reduction. At C = 2 most of maximum power reduction is achieved, but beyond C = 3 there is very little further reduction ...

SmallScale Tests to Characterise Ore Grindibility

The work index series (ball mill, rod mill, and MacPherson autogenous) and pilot plant tests require relatively more weight (for a given top size) because they are run until a steadystate is achieved, which involves replacing the mill charge several times throughout the test. The Bond tests are typically run for a minimum of seven cycles, while the MacPherson and pilot plant tests are ...
