Principles of Grinding in Ball Mills Orbis Machinery, LLC. 26/10/2018 There is a very specific operating speed for the most efficient grinding. Depending upon the Mill’s speed, there is a point in which the load along the wall of the cylinder will break free and the grinding media will begin to cascade through several layers of the material.
