Uses of a Ball Mill Liner. The role of a ball mill liner is to give the mill heads protection against wear and tear thus increasing their lifetime and creating optimal grinding efficiency. The design of a ball mill liner depends on the drilling pattern of the mill heads, the rpm speed of the mill, the maximum grinding diameter of the media and the percentage of media filling.

A secondary mill will require the high surface contact with more of the grinding motion that the lower cascade brings. This means that the secondary mill will have LOW PROFILE ROD MILL LINERS in them. If it is a ball mill being used as the primary grind the size of the grinding media will be increased, this is to increase their impact. A HIGHER ...

Such mills are common in South African operations; mills are sometimes referred to as tube mills or ROM ball mills and are also operated both autogenously and semiautogenously. Many of these mills operate at higher mill speeds (nominally 90% of critical speed) and often use "grid" liners to form an autogenous liner surface.
