### Variables in Ball Mill Operation Paul O. Abbe®

Mill Speed is one variable that can often be easily changed with a variable frequency drive (VFD). The starting point for mill speed calculations is the critical speed. Critical speed (CS) is the speed at which the grinding media will centrifuge against the wall of the cylinder. Ball milling is one of the few unit operation that improves
