How Ball Mill Ore Feed Size Affects Tonnage Capacity
The rod mill was needed to reduce feed size to the ball mill because crushing plant output was normally coarser than 80 passing 10000 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
