Ball Mill Critical Speed Mineral Processing Metallurgy

Jun 19, 2015 · C.S. = 76.63 / 11^0.5 = 23.1 rpm. Ball and SAG Mills are driven in practice at a speed corresponding to 60-81% of the critical speed, the choice of speed being influenced by economical considerations. Within that range the power is nearly proportional to the speed. Mill rotating speed impacts grinding rates

Sagmillingcom Mill Critical Speed Determination

Mill Critical Speed Determination. The "Critical Speed" for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell's inside surface. This is the rotational speed where balls will not fall away from the mill's shell. Result #1: This mill would need to spin at RPM to be at 100% critical speed

Ball Mill Operating Speed Mechanical Operations Solved

The critical speed of ball mill is given by, where R = radius of ball mill; r = radius of ball. For R = 1000 mm and r = 50 mm, n c = 30.7 rpm. But the mill is operated at a speed of 15 rpm. Therefore, the mill is operated at 100 x 15/30.7 = 48.86 % of critical speed. If 100 mm dia balls are replaced by 50 mm dia balls, and the other conditions are remaining the same, Speed of ball mill = [0.4886/(2p)] x [9.812/(1 - 0.025)] 0.5 = 14.8 rpm
