The ball mill liner is a crucial component of the ball milling equipment. The most commonly used materials for ball mill liners are high manganese steel, including high chrome cast iron and other materials. The installation of mill liners inside the mill ensures that there is no direct contact between the grinding media and the mill shell. This reduces wear and tear on the mill shell, thereby prolonging the service life of the ball mill. Additionally, the shape of the mill liner can affect the movement of the grinding media, thereby optimizing the grinding effect.
