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.A major ball mill manufacturer presents a persuasive case for choosing this proven — and improved — design over other types. Over many years of use, shell-supported ball mills similar to those pictured above have proven their efficiency and reliability, and a large number of mining projects would not have been viable without them.
