Autogenous and Semi-Autogenous Mills

Rely on our proven track record of S and Mill superiority. Since the early 1980s, we have been designing and manufacturing Semi-Autogenous (S) and Autogenous () Grinding Mills under the Fuller-Traylor brand. Semi-autogenous grinding uses a minimal ball charge in the range of 6-15% while autogenous grinding uses ore only.

Flexible milling and grinding solutions that last

For the mining industry, our semi-autogenous (S) grinding mill uses a minimal ball charge in the range of 6-15 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous () grinding mills involve no grinding media as the ore itself acts as the grinding media.
