• ##### 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.
