Secondary Grinding Ball Mills In secondary ball milling abrasive and corrosive conditions predominate The smaller balls 2 65 mm typically used in secondary milling environments effectively reduce the impact component of wear to the point where grinding media must be primarily designed to reduce abrasive and corrosive wear Place the green mix into a ball mill with nonsparking milling media It should be milled for at least 34 hours It should be milled for at least 34 hours Summary It has many uses including prime dusting a general ingredient in some compositions and preventing stars from sticking together during manufacture Steel Ball Mills Lined Ball Mills Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800s The basic construction of a ball mill is a cylindrical container with journals at its axis The cylinder is filled with grinding media ceramic or metallic balls
