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 …
