A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell’s inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula The mill speed is typically defined as the percent of the Theoretical

MoreBall mill critical speed derivation . Ball Mills Mine EngineerCom ball mill critical speed derivation,If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill The point where the mill becomes a centrifuge is called the Critical Speed, and dragThe second is air drag, which.

MoreDerivation Of The Expression For Critical Speed Of A Ball Derivation Of The Expression For Critical Speed Of A Ball Mill The critical speed of the mill, c, is defined as the speed at which a single ball will just remain against the wall for a full cycleAt the top of the cycle 0 and fc fg 85 mp 2 cdm 2 mpg 86 c 2g dm 12 87 the critical speed is

MoreThe 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.
