There are many different designs and styles of ball mill liners. As with grinding balls local economics and ultimately operating costs determine the best design and material to use. The initial set of liners is rarely the final design selected. Based upon individual experience, mill superintendents develop preferences for liner designs.

Rubber liners absorb the impact of the larger grinding media and thus protecting the mill structure and prolonging it's life. Weight: Rubber weighs about 15% of an equivalent volume of steel. This means that a rubber liner system reduces the load on the mill structure and also reduces the basic power draw.

For large mills, using 125 to 140 mm (5 to 51/2 in.) feed ball size, conventional new lifterliner dimensions are around 300 to 350 mm (12 to 14 in.) overall height above the shell, with around 100 mm (4 in.) plate thickness and around 150 mm (6 in.) top width. Detailed design depends on individual mill circumstances.

The way the rubber technology has evolved over the last 30 years, I would tell you that you can use rubber in virtually any ball mill, pebble mill, and most rod mills. In SAG mills the limits are in the size of the mills (larger tend to go to steel) and the top size of the balls (larger tend to go to steel).
