    The "Critical Speed" for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell s inside surface. This is the rotational speed where balls will not fall away from the mill s shell. Result #1 This mill would need to spin at RPM to be at 100 critical speed.

  • Critical rotation speed for ball-millingScienceDirect

     · It has been commonly accepted that the critical rotation speed is a function of a ball radius and a jar diameter. The results of the present work however show that the critical rotation speed significantly depends on ball-containing fraction in jars and approaches a value asymptotically as the ball-containing fraction approaches to one.
