Ball Mills - an overview ScienceDirect Topics
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.
An analysis of fine dry grinding in ball mills - ScienceDirect
The kinetics of dry grinding of several cement clinkers and two coals were investigated in a laboratory tumbling ball mill. The kinetic process is first-order at first but the rates of breakage decrease as fines accumulate in the bed.
