With this high aspect ratio SAG mills generate both thrown and cascading ballmilling actions with shell linings shaped to lift and to throw alloy steel grinding balls of up to 150 mm 6 in. in diameter. These actions apply crushing attrition and abrasion comminution processes to reduce primarycrushed ores down to ball
