Ball Mill vs Rod Mill How To Choose Ball Mill or Rod

Ball Mill vs Rod Mill How To Choose Ball Mill or Rod

Ball mill uses steel ball as grinding medium. Because the steel ball is in point contact with the ore, the grinding products are of high fineness, and the particle size of the products is relatively fine, which is prone to over grinding, so ball mill is not suitable for the re-selection production line in ore dressing.

Ball Mills vs Rod Mills

Ball Mills vs Rod Mills

When the mill is rotated without feed or with very fine feed, the rods are in parallel alignment and in contact with one another for their full length. New feed entering at one end of the mill causes the rod charge to spread at that end. This produces a series of wedge shaped slots tapering toward the discharge end. The tumbling and rolling rods expend most of their crushing force on the ...
