Crushing Plant Flowsheet & Design-Layout

The idea behind a coarse ore stockpile (COS) is to reduce material hardness and grade variations in the mill. There is enough material change to detect from the incoming and outgoing material given the relatively small size of most COSs. If we achieve a perfect, uniform blend, the problem would be solved.
