    The "Critical Speed" for a grinding mill is defined as therotational speedwhere centrifugal forces equal gravitational forces at the mill shell's inside surface. This is therotationalspeed 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
