### 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

energy required to operate large grinding mills, such as ball and rod mills, AG and SAG mills [5]. The influence of feed size on mill performance naturally follows from the fact that a considerable part of the grinding media (especially in autogenous mills) derives from the feed ore. Any change in the feed distribution will therefore result in a change in the grinding media size
