Key considerations when selecting a mill lining system

SAG mills generate higher levels of impact reduction and ball mills higher levels of abrading action. A mill lining system serves two purposes: to protect the mill shell from wear caused by the impact and abrasion of the mill charge, and to elevate and tumble the mill contents in the necessary manner to create a grinding action.
