Mill Critical Speed Calculation. At the highest speed the outer layer of discs tends to stick to the wall, showing a tendency to centrifuge. The effect of mill speed on energy input was studied in a mill of 0.3-m diameter and 0.25-m long with 40 charge filling. The total charge weight was 54 kg. The variation in torque with speed

2012-11-26The Critical Speed is used for the determination of ball mill ideal operating speed. But for comparison, rod mills would operate between 50 to 95 of the critical speed. The faster the mill speed, the greater the wear on the rods and liners. So, the general rule of thumb for rod mills is to operate no faster than the speed that will obtain the
