    How Ball Mill Ore Feed Size Affects Tonnage amp Capacity

    Jul 26, 2017 The rod mill was needed to reduce feed size to the ball mill because crushing plant output was normally coarser than 80 passing 10,000 microns. Such feed causes power inefficiency if fed directly to a ball mill. Even though the rod mill could be a relatively inefficient device for both energy and metal consumption, as was evidenced by Bond, it ...
