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 ...
The point where the mill becomes a centrifuge is called the "Critical Speed", and ball mills usually operate at65% to 75% of the critical speed. Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns.

Thecritical speed of ball millis given by, where R = radiusof ball mill; r = radiusof ball. For R = 1000 mm and r = 50 mm, n c = 30.7 rpm. But themillis operated at aspeedof 15 rpm. Therefore, themillis operated at 100 x 15/30.7 = 48.86 % ofcritical speed.
Mill Critical Speed Determination. The "Critical Speed" for a grinding mill is defined asthe rotational speedwhere 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. Result #1: This mill would need to spin at RPM to be at100% critical speed.
