Effect of Mill Speed on the Energy Input In this experiment the overall motion of the assembly of 62 balls of two different sizes was studied. The mill was rotated at 50, 62, 75 and 90% of the critical speed. Six lifter bars of rectangular crosssection 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 ...
The formula for critical speed is CS = 1/2π √(g/(Rr) ... Ball milling is one of the few unit operation that improves with increasing mill diameter. If acceptable results can be obtained with a 12" jar mil, then good result will certainly be obtained with a 72" diameter mill. Of course there is the possibility of over milling.
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.
