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 = 30.7rpm.But the mill is operated at a speed of 15rpm.Therefore, the mill is operated at 100 x 15/30.7 = 48.86 % of critical speed

The "Critical Speed" for a grindingmillis defined as the rotational speed where centrifugal forces equal gravitational forces at themillshell's inside surface. This is the rotational speed whereballswill not fall away from themill'sshell. Result #1: Thismillwould need to spin at RPM to be at 100%critical speed
