determine critical speed ball mill

The critical speed of ball mill is given by, whereR = radius of ballmill;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

Effect ofMill Speedon 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 thecritical 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

Mill Critical Speed Determination. The "Critical Speed" for a grinding mill is defined asthe rotational speed where centrifugal forces equal gravitational forces at the mill shell's inside surface.This is the rotational speed where balls will not fall away from the mill's shell.
