May 22 2019 The ball mill consists of a metal cylinder and a ball The working principle is that when the cylinder is rotated the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force although the calculation formula of the limit ball

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
