For a ball mill to work critical speed must be achieved. Critical speed refers to the speed at which the enclosed balls begin to rotate along the inner walls of the ball mill. If a ball mill fails to reach critical speed the balls will remain stationary at the bottom where they have little or no impact on the material.
