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.

Once the bearing has worn through this layer, rapid and catastrophic wear occurs to the softer metal below. This type of fatigue failure is called "spalling." This kind of damage causes the metal to come off in flakes. If a bearing overheats, the hot lubricant breaks down and can cause scoring and even etching of the bearing surfaces.
