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.
