Semiautogenous grinding mills SAG mills . 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
Coarse Grind – Coarser than 80% passing 106 µm. If determined to be reasonably power-efficient, single stage SAG milling is likely to be the most profitable grinding circuit design. 2. Medium Grind – 80% passing size between 106 and 75 µm. To mill in single stage SAG configuration, the feed must be consistent, not too coarse or too fine. The
Semi-autogenous Outotec SAG mills, as they are often called, can accomplish the same size reduction work as two or three stages of crushing and screening.

SAG is an acronym for Semi-Autogenous Grinding. SAG mills are essentially autogenous mills, but utilize grinding balls to aid in grinding like in a ball mill. A SAG mill is generally used as a primary or first stage grinding solution. Attrition between grinding balls and ore particles causes grinding …
Semi-autogenous grinding mills (SAG mills) are tumbling mills that most commonly have a shell diameter-to-length ratio of around two. With this high aspect ratio, SAG mills generate both thrown and cascading ball-milling actions with shell linings shaped to lift and to throw alloy steel grinding balls of up to 150 mm (6 in.) in diameter. These
Since the early 1980s, we have been designing and manufacturing Semi-Autogenous (SAG) and Autogenous (AG) Grinding Mills under the Fuller-Traylor brand.
