Mill Critical Speed Calculation

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 ...

Ball Mill Operating Speed - Mechanical Operations Solved ...

The critical speed of ball mill is given by, where R = radius of ball mill; r = radius of ball. For R = 1000 mm and r = 50 mm, n c = 30.7 rpm. But the mill is operated at a speed of 15 rpm. Therefore, the mill is operated at 100 x 15/30.7 = 48.86 % of critical speed.

Critical rotation speed for ball-milling - ScienceDirect

Aug 03, 1999· To examine the dependence of critical rotation speed on ball-containing fraction, we measured critical speeds at various ball-containing fractions from 0.3 to 0.95 stepped by 0.05. Since at lower fraction than 0.3 we could not observe the centrifugal motion, we chose this fraction range. A jar of ball-mill consists of a cylinder and two lids.
