3. Differences on grinding medium between wet ball mill and dry ball mill. On the grinding medium, the dry ball mill only needs to join the steel ball, while the wet ball mill needs to add liquid to participate in grinding except for steel ball. The commonly used proportion: steel ball: material: water = 4:2:1.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

A mill is a machine that is used to break down solid materials into smaller pieces by cutting, grinding, or crushing. The process of milling includes the use of force that acts on a material to tear it apart and reduce its size. Milling improves the performance of ingredients, and the products made from them.
