The basics of grinding circuit optimisation
unutilised ball mill power; and/or a capacity to tolerate a coarser grinding circuit product. The purpose of the secondary crusher, which can be operated in open or closed circuit, generally receiving a scalped feed, is to reduce all or part of the SAG mill feed to nominally 80 per cent passing 25-50 mm. This reduces the amount
