What's the difference of Ball mill, SAG mill, AG mill?
The Sag mill uses lifting plates along the interior of the drum, which lift material throughout the rotations, causing them to fall onto one another to promote crushing. A ball mill has many steel or porcelain balls put in a drum to grind the feed between balls and between the balls and drum inner wall as the drum rotates.
Different types of grinding mills
The difference between autogenous and SAG mills is, it uses balls to grind like ball grinding mill. SAG mills have built-in lifting plates inside the drum. When the drum rotates, the lifting plates lift the materials and the balls to the top and release them back to the surface. It causes the materials to mix at a primary level.
