SAG mills (semiautogenous grinding mills) liming
Semiautogenous mills or SAG mills, as they are often called, can accomplish the same size reduction work as two or three stages of crushing and screening. Often used in grinding at modern mineral processing plants, SAG mills reduce the material directly to the desired final size or prepare it for the following grinding stages.

What's the Difference Between SAG Mill and Ball Mill
SAG mills grinding media includes some large and hard rocks, filled rate of 9% 20%. SAG mill grind ores through impact, attrition, abrasion forces. In practice, for a given ore and equal processing conditions, the AG milling has a finer grind than SAG mills. How does a sag mill work? The working principle of the selfgrinding machine is basically the same as the ball mill, the biggest
