Ball Mill Critical Speed

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 ...

Critical rotation speed for ball-milling

 · The critical rotation speed of the jar significantly depends on the ball-containing fraction, as seen in Fig. 3, and is not determined by Eq.(1)for given radii of the jar and the ball only.The critical rotation speed is close to the value determined by Eq.(1), as the ball-containing fraction approaches to one, since concentric circles approximately represent the trajectories of balls as the ...
