Ball Mill Critical Speed

Ball Mill . Ball Mills have been successfully run at speeds between 60 and 90 percent of critical speed However most Ball Mills operate at speeds between 65 and 75 percent of critical speed 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 A Ball.

Ball Mill Explained Savree

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.
