Jun 09, 2017 Ball Mills Mine EngineerCom. The larger the diameter the slower the rotation If the peripheral speed of the mill is too great it begins to act like a centrifuge and the balls do not fall back but stay on the perimeter of the mill The point where the mill becomes a centrifuge is called the Critical Speed and ball mills usually operate at 65 to 75 of the critical speed Ball Mills.

Mar 10, 2020 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. Ball Mills vs.

Critical speed is defined as the point at which the centrifugal force applied to the grinding mill charge is equal to the force of gravity. At critical speed, the grinding mill charge clings to the mill inner surface and does not tumble. Most ball mills operate at approximately 75 critical speed, as this is determined to be the optimum speed.
