The critical speed n (rpm) when the balls are attached to the wall due to centrifugation: Figure 27 Displacement of balls in mill n = 423 D m where D m is the mill diameter in meters The optimum rotational speed is usually set at 6580% of the critical speed These data are approximate and may not be valid for metal particles that tend to agglomerate

#### Ball Mill Operating Speed Mechanical Operations

2020-6-13  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

#### Ball Mill Critical Speed Mineral Processing &

2021-2-19  A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell’s inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula The mill speed is typically defined as the percent of the Theoretical

#### RPMs on a ball mill and a star rolling machine

Okay, I'm "considering" building a combo machine for ball milling and star rolling. The thing I'm confused about is the RPM of the drums. I always thought a ball mill should be fairly slow because rock tumblers that I've seen are fairly slow maybe 60 revs per minute. I guess I'm wrong. I've seen recommendations of much higher speeds. Of
