Full Form of SAG in Grinding Mills | FullForms
A SAG mill is generally used as a primary or first stage grinding solution. SAG mill is a tumbling mill with a large rotating drum, is filled with ore, water, and steel grinding balls. The result is a fine slurry. The mill is so named because the rock itself does some of the grinding.
