Ball mill used in the process of fining material Translate this pagebut stay on the perimeter of the mill. Ball mills usually operate at 65% to 75% of the critical speed. Ball mill has been used to produce fine particles from a coarse feedCritical speed definition and meaning Collins English The crushing of particles in a traditional mill is generally accomplished by rotating the mill near the critical speed. Running a mixer in excess of the critical speed can cause destructive mechanical vibrations. Critical speed is the speed at which unwanted vibration happens when a vessel is

Cement mill WikipediaThe critical speed (rpm) is given by: n C = 42.29/ √ d, where d is the internal diameter in metres. Ball mills are normally operated at around 75% of critical speed, so a mill with diameter 5 metres will turn at around 14 rpm. The mill is usually divided into at least two chambers (although this depends upon feed input size mills including History&ensp·&enspBall Mills Mine Engineer.ComThe point where the mill becomes a centrifuge is called the "Critical Speed" and ball mills usually operate at 65% to 75% of the critical speed. Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns.
