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.

Grinding efficiency is greatly affected by the classification efficiency and the mill operating parameters such as mill speed, media charge, slurry density and viscosity. Pebble mills are also used for fine grinding. They are similar to ball mills except that they are charged with 25 mm to 100 mm pebbles rather than steel balls.

Mineral beneficiation processes chain incorporate several unit operations operated in continuous manner. In the crushing line the solid material (typically ore) is comminuted to the particle size of centimetre scale. In grinding line, water is added and the particles are processed further into micrometer scale using grinding mills.
