SAG Mill Liner Types - MGS Casting
The style of a SAG mill liner is driven by the material of building and construction and also the application, as well as limited by casting, molding, and taking care of constraints. For huge mills with wide inlet trunnions, in excess of 1.5 m, liner handling types of equipment are currently in common usage, and also this has actually permitted the development of large …
What's the Difference Between SAG Mill and Ball Mill ...
The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...
Semi-autogenous grinding (SAG) mill liner design and ...
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
