grinding mill critical speed calaulator Simone Pachur grinding mill critical speed calaulator 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 shells inside surface This is the rotational speed where balls will not fall away from the mills shell· 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 the figure, the overall motion of the balls changes with the mill speed inasmuch as the shoulder height shifts with the speed and the charge pressureMill Critical Speed CalculationThe "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 Result #1: This mill would need to spin at RPM to be at 100% critical speed Result #2: This mill' : Mill Critical Speed Determination
