ATTRITORS AND BALL MILLS HOW THEY WORK Robert E. .The critical speed of a ball mill is calculated as divided by the square root of the radius in feet. The rotational speed is defined as a percentage of the critical speed. Smaller diameter mills rotate faster (same % of critical speed) than larger mills. A higher % of critical speed yields
It's the high time to notice Ball Mill's Critical Speed ...The ball mill rotating speed is called critical speed when the outmost layer balls just rotate with the barrel and don't fall. The critical speed of various ball mills is in direct proportion with its diameter, the absolute figure of critical speed is hard to calculated, and now only the calculation formula on critical speed in theory is widely used.
