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...Semi autogenous mill is usually called SAG mill, which can replace some crushing and screening operations while grinding. It is a common equipment in modern concentrators, which can directly produce finished products or provide materials for the operation of the lower ball mill. The grinding medium (steel ball) of semi autogenous mill is 6-15%.
