how to calculate critical speed of a ball mill
Ball Mill Critical Speed
Ball mills have been successfully run at speeds between 60 and 90 percent of critical speed, but most mills operate at speeds between 65 and 79 percent of critical speed Rod mills speed should be limited to a maximum of 70% of critical speed and preferably should be in the 60 to 68 percent critical speedCalculate Critical Speed Ball Mill Commonly the ball mill speed is calculated as 77 of ball mills mine engineermnformation on ball millsif the peripheral speed of the mill is too great it begins to act like a centrifuge and the balls do not fall back but stay on the perimeter critical ball mill speed calculatormill calculate the critical speed of the ball mill

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 crosssection 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 theThe mill critical speed will be calculated based on the diameter (above) less twice this shell liner width Mill Actual RPM: Enter the measured mill rotation in revolutions per minute Result #1: This mill would need to spin at RPM to be at 100% critical speed : Mill Critical Speed Determination
