Critical Speed. Critical speed is defined as the point at which the centrifugal force applied to the grinding mill charge is equal to the force of gravity. At critical speed, the grinding mill charge clings to the mill inner surface and does not tumble. Most ball mills operate at approximately 75% critical speed, as this is determined to be the ...

The critical speed n (rpm) when the balls remain attached to the wall with the aid of centrifugal force is: n = 42.3 D m. where D m is the mill diameter in meters. The optimum rotational speed is usually set at 65%–80% of the critical speed. ... In the last decade vertical mills have taken an increasing share of the cement milling market, not ...

the optimal operating speed depends mainly on filling degree, grinding media size and type of liners. 3.1 critical speed: the critical speed of a tube mill is that speed of rotation at which the centrifugal power neutralizes the force of gravity which influences the grinding balls, the grinding balls don't fall and therefore don't perform …

For 70% critical mill speed, Fig. 7 shows variation of S ** for 20/28 mesh size fraction of quartz with particle load at three levels of ball load, J: 0.2, 0.3 and 0.4. It can be seen that all three curves exhibit a maxima. The U value corresponding to the maxima, U *, decreases as the ball load increases.

The speed has to generate enough "centrifugal force" to make the grinding media lift up on the shell lining to a height of about two-thirds of the diameter of the shell with least sliding. The optimum speed of the mill is about 0.6 to 0.75 times the "critical speed". The critical speed of the mill is defined as the minimum speed at
