#### Ball Mill Critical Speed Mineral Processing &Metallurgy

The critical speed of a rotating mill is the RPM at which a grinding medium will begin to centrifuge, namely will start rotating with the mill and therefore cease to carry out useful work. Ball mills have been successfully run at speeds between 60 and 90 percent of critical speed, but most mills operate at speeds between 65 and 79 percent

#### What is a ball mill? What are its uses and advantages? Quora

A ball mill is a grinding device that is used to turn material into fine powder. Ball mills are cylindrical in shape, and are often the grinder of choice when it comes to mashing paints, ores, ceramic materials, and certain hard chemicals.

#### Planetary Ball Mill 911Metallurgist

The high energy of these mills is derived from the very high rotation speeds that are achievable. For example, Salimon et al. used their planetary ball mill at a rotation speed of 1235 rpm corresponding to the mill energy intensity of 50 W/g. It has been reported that some of these mills can be used at rotation speeds greater than 2000 rpm.
