More### Ball Mill Critical Speed - 911 Metallurgist

2015-6-19 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 of critical speed.

More### RPMs on a ball mill and a star rolling machine

Okay, I'm "considering" building a combo machine for ball milling and star rolling. The thing I'm confused about is the RPM of the drums. I always thought a ball mill should be fairly slow because rock tumblers that I've seen are fairly slow - maybe 60 revs per minute. I guess I'm wrong. I've seen recommendations of much higher speeds. Of
