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. ... the formula used for critical speed is: n c =76.6(d-0.5) where, n c is the critical speed,in.
The ball mill finish calculator can be used when an end mill with a full radius (a ball mill) is used on a contoured surface. the tool radius on each side of the cut will leave stock referred to as a scallop. the finish of the part will be determined by the height of the scallop, amd the scallop will be determined by the stepover distance.

Two-product formula. given the mass and component balance equations : f = c + r. ff = cc + rr. mass yield (y) can be solved as a function of the stream, assays which yields the two-product formula: r = f- c. ff = cc + r (f – c) mass yield formula.
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.
