Optimum Filling Ratio For Ball Mill

03 3keeping the suitable steel ball filling ratio under certain rotating speed the larger steel ball filling ratio is the more hits of materials and the larger grinding area is so the energy consumption is also large it easily leads to the change of steel ball motion state which reversely reduces the hit effect of large particle material.
