TECHNICAL NOTES 8 GRINDING R. P. King
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 cycle. At the top of the cycle =0 and Fc Fg (8.5) mp & 2 cDm 2 mpg (8.6) & c 2g Dm 1/2 (8.7) The critical speed is usually expressed in terms of the number of revolutions per second Nc & c 2 1 2 2g Dm 1/2 (2×9.81)1/2
