Grinding is a subprocess of finely grinding ore in advance, such that the ground output can be physically separated into iron ore and impurities in the downstream subprocess. In many cases, an autogenous mill (AG mill) or a semiautogenous mill (SAG mill) is used for the primary grinding, and a ball mill is used as the secondary for further

Reason: This is a common problem mining ball mills face, resulting in low productivity and low ore processing efficiency. One reason may be the improper design of the grinding chamber, which affects the flow of materials and reduces grinding efficiency. Additionally, worn or damaged liners can hinder the grinding process by reducing the effective impact between the ball and the material.
