Ball Mill Critical Speed Mineral Processing

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 Formula For Critical Speed Of A Ball Mill Of the ballthe smallest theoretically possiblecan be referred to as criticalor example on fig 1 for the dotted curve relating to the original feeding of 10 0 mm the size of the ball d 9 mm evidently will be critical having o loaded a mill which has balls of the critical Ball Mill Design Critical Speed Formula The speed of the mill was kept at 63% of the critical speed The face angle was varied from 90 to 111 degrees for the three types of configuration 1, 2 and 4, as shown in the figure Also, the height of the lifter bar in configuration 3 was changed to observe the trajectoryMill Critical Speed Calculation
