Ball Mill VS Rod Mill - Xinhai

Apr 7, 2016 ... For details, the grinding theory of ball mill and rod are different in many ways. For ball mill, the grinding force of steel ball to ore is less than the impact, because the contact area is small between balls and mineral. Thus, the throwing motion of ball can produce a large impact, but it need a high rotate speed...
