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. Obviously no milling will occur when the media is pinned against the cylinder so operating speed will be some percentage of the CS. ... Ball milling is one of the ...
