what is the critical speed of a ball mill
The critical speed (Nc) of a ball mill is the rotational speed at which the centrifugal force on the grinding media (balls) inside the mill is equal to the force of gravity acting on them. At this critical speed, the grinding media are held against the inner wall of the mill by centrifugal force, preventing them from falling freely and causing ...
