Benchmarking Fimiston Ball Mills SAGMILLING.COM

† The appendix of the paper lists the mill speed as 12.5 RPM. The mill is fixed speed, so the %critical speed is only a function of mill effective diameter (as liners wear). Doing the math (neglecting the balls) gives a 68.4% critical speed. The ball mill belly length can be achieved with a 18 degree head angle and 1.9 m trunnion diameter.

Question On Critical Speed Of Ball Mill

2012-11-26The Critical Speed is used for the determination of ball mill ideal operating speed. But for comparison rod mills would operate between 50 to 95 of the critical speed. The faster the mill speed the greater the wear on the rods and liners. Trade Assurance. Pollo Mining Heavy Industries Co., Ltd.
