In a turning operation, an aluminum workpart is reduced from a radius of 26mm to a radius of 24mm. If the lathe is set at 1500rpm the tool edge lasts just long enough to cut 50 parts taking 4 minutes each. If the lathe is slowed to 1/3rd that speed (500rpm) the tool can now make it through an amazing 1400 parts, but it takes 3times longer per part.

formula for critical speed of a ball mill

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. Therefore, the mill is operated at 100 x 15/30.7 = 48.86 % of critical speed. Get Price
