If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill. The 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.

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 critical speed. Result #2: This mill's ...

In short, you never want the 1/2 critical speed of the driveshaft to occur within the 50 to 70 MPH range of the vehicle. WARNINGS. An unbalanced driveshaft can experience a critical speed failure in your balancer at an RPM that is lower than the "Safe operating RPM" figure shown below.
