End liners for ball mills conform to the slope of the mill head and can be made of rubber, alloyed cast steel or wear resistant cast iron. To prevent racing and excessive wear endliners for ball mills are furnished with integral radial ribs or with replaceable lifters or with both.
The performance of a ball mill is known to be affected by the design of the liners. A proper liner must key the ball charge to the mill shell in order to maximize the tumbling action with a minimum of slippage, and at the same time it must protect the mill shell from damage. There are two important features that are common to all three figures.
Mill liners serve several critical purposes in the mining and milling industry, including: Protecting the mill's shell and internal components from damage caused by the grinding process Reducing the amount of downtime and repairs required for maintenance Improving grinding efficiency by promoting optimal grinding media movement within the mill
