.:. Mill Critical Speed Determination

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 ...

Critical rotation speed for ballmilling

 · After this work, the critical rotation speed has never been reexamined. At the critical rotation speed the balls are placed stationarily with respect to the inner wall of the jar, and cannot contribute grinding. However, when the mechanics of the ballmill are examined in detail, we must evaluate those commonly accepted phenomena also.
