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. To achieve this ...

A critical speed is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell's inner surface. The ball filling was then set to 5%, 10% and % of the mill volume. The shell liners and enclosure of the pilot mill were all made with mild steel material. The material properties are summarised in Table 1.
