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

Autogenous Mill | SpringerLink
The ore particles smaller than 80 mm but bigger than 20 mm have poor grindability and they cannot be easily ground by big lump ore, so such material is usually called "hard-to-grind ore" or "hard rock." To crush the hard-to-grind ore, sometimes steel balls can be added into the autogenous mill. This type of mill is semi-autogenous mill.
