coal, grinding, issues and policy, milling, powders, steel Abstract: Tube mills use steel balls as grinding media. Due to wear in the abrasive environment it is necessary to charge new balls periodically to maintain a steady balanced ball charge in the mill.
Rely on our proven track record of SAG and AG Mill superiority. Since the early 1980s, we have been designing and manufacturing SemiAutogenous (SAG) and Autogenous (AG) Grinding Mills under the FullerTraylor brand. Semiautogenous grinding uses a minimal ball charge in the range of 615% while autogenous grinding uses ore only.

Improved wear resistant materials can be installed for grinding media, especially in ball mills. Grinding media are usually selected according to the wear characteristics of the material. Increases in the ball charge distribution and surface hardness of grinding media and wear resistant mill linings have shown a potential for reducing wear as well as energy consumption.
