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

SAGMILLING.COM .:. Mill Critical Speed Determination

The "Critical Speed" for a grinding mill is defined as the 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. Mill Inside Diameter: Enter the mill diameter inside the shell (excluding liners). Most mill sizes are reported by vendors are outside the

2.1.2 Critical Speed: If the peripheral speed of the mill is very high, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill and that point is called the "Critical Speed” (n c).This phenomenon is called centrifuging. Ball mills usually operate at 65% to 75% of the critical speed. The critical speed is calculated as under [5]. R r g 2 1 n c

Working with a 7.32 m diameter and 3.66 m long mill, Napier-Munn et al. [4] observed that the breakage rate for the finer size fractions of ore (say 0.1 mm) at lower speeds (e.g., 55% of the critical speed) was higher than that observed at higher speeds (e.g., 70% of the critical speed). For larger sizes of ore (in excess of 10 mm), the breakage rate was lower for mills rotating at 55% of the
