20121126&ensp·&enspThe 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 thu for rod mills is to operate no faster than the speed that will obtain the

### Drum mills by SIEBTECHNIK TEMA Comminution Equipment

The main operating conditions decisive for pulverization are the drum speed and filling conditions. The usual speeds are in the range between 70% to 80% of the critical speed. In exceptional cases, both lesser speeds (friction effect) as well as greater speeds (impact effect) are selected in the range of 60% to 90% of the critical speed.

### SAGMILLING.COM .:. Mill Critical Speed Determination

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.
