using steel grinding ball mill

Secondary Grinding – Ball Mills In secondary ball milling, abrasive and corrosive conditions predominate. The smaller balls [< 2½”, (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 reduceabrasive and corrosive wear.
