Get PriceABall Mill CriticalSpeed (actuallyball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at themillshell’s inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside amillas speed varies. Use our online formula Themillspeed is typically defined as the percent of the Theoretical ...
Effect ofMillSpeed on the Energy Input In this experiment the overall motion of the assembly of 62 balls of two different sizes was studied. Themillwas rotated at 50, 62, 75 and 90% of thecriticalspeed. Six lifter bars of rectangular cross-section were used at equal spacing. The overall motion of the balls at the end of five revolutions is shown in Figure 4. As can be seen from the ...
