Low speed: At low speed, the mass of balls will slide or roll up one over another and will not produce a significant amount of size reduction. High Speed: At high-speed balls are thrown to the cylinder wall due to centrifugal force and no grinding will occur. Normal speed: At Normal speed balls are carried almost to the top of the mill …

Ball mills are commonly used in single stage fine grinding, regrinding, and as the second stage in two-stage grinding circuits. Ball mills are available in both wet and dry designs, depending on the application. Ball mills have been constructed with standard final product diameters ranging from 0.074 mm to 0.4 mm in diameter.

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 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
