sagmilling.com . . mill critical speed determination
Enter the width of a mill shell liner. Note this is not the width of a lifter! You may use the Mill Liner Effective Width calculation to determine this value. The 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

ball mill operating speed mechanical operations solved
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
