# critical rotational speed ball mill

### Recommended Ball Mill Speed Liner Configuration

Mill critical speed is defined as that rotational speed at which an infinitely small particle will centrifuge assuming no slippage between the particle and the shell. The critical speed Nc in revolutions per minute is a function of the mill diameter D expressed as Nc = 42.3/√D (meters) or Nc = 76.63/√D (feet)
