Critical Speed Of Ball Mill 76 6

† 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. Our main products include crushing equipment, sand making equipment, beneficiation equipment, grinding equipment and building materials equipment, welcome to purchase;
