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. If 100 mm dia balls are replaced by 50 mm dia balls, and the other conditions ...

Planetary Ball Mills - High-Performance all-rounders in routine laboratory work. ... Rotational speed of the grinding bowls up to 2200 rpm ; Grinding has never been safer due to revolutionary new grinding bowl clamping – without additional clamping and the risk of incorrect operation.

A ball mill can grind and homogenize small sample volumes down to the nano range. The Emax is an entirely new type of ball mill for high energy input.

Optimizing the Ball Mill's RPM Make sure the whole roller assembly now looks as it originally did, and rotates freely. There you go: A larger, 3/4-inch diameter drive roller, simple as that. Test-run the mill with a jar on it, and verify that the speed of the jar's rotation has increased to approximately 80-90 RPM.
