• #### TECHNICAL NOTES 8 GRINDING R. P. King

Since critical speed is larger at smaller radii the centrifuging layer gets thicker and thicker as the speed increases until the entire charge is centrifuging and the net power draw is zero. The effect of mill charge is primarily through the shifting of the center of gravity and the mass of the charge.

At what speed will the mill have to be run if the 100 mm balls are replaced by 50 mm balls, all the other conditions remaining the same? Calculations: 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.
