Tumbling ball mills or ball mills are most widely used in both wet and dry systems, in batch and continuous operations, and on small and large scales. Grinding elements in ball mills travel at different velocities. Therefore, collision force, direction, and kinetic energy between two or more elements vary greatly within the ball charge.

25.06.2004The motion of balls in wet milling is affected by the slurry, so the following two parameters; the drag force FD and the buoyancy are introduced. The value FD is calculated by Eq. (2), where Cd denotes the drag coefficient, A is a projection area of a ball, ρs is the density of slurry and ur is the relative velocity between a ball and slurry.
