Sag Mill And A Closed Circuit Ball Mill

Rely on our proven track record of sag and ag mill superiority.Since the early 1980s, we have been designing and manufacturing semi-autogenous (sag) and autogenous (ag) 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.

We are committed to building crushing, industrial grinding, ore processing and green building materials, and provides intelligent solutions and mature supporting products.
