Proof Of Critical Speed Equation In Ball Mill. ensp0183enspThe critical rotational speed ratio 207 of the vessel, defined as the ratio of the operating speed n to the ideal critical speed nc 2.35 s 2261, i.e., 207 nnc, which was determined as nc 2gD 0.52207 g gravity acceleration, D vessel diameter from the equilibrium of gravity and centrifugal force acting on a ball.

### derive the equation of critical speed of ball mill

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 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 ...
