Several large tonnage copper porphyry plants in Chile use an open-circuit SAG configuration where the pebble crusher product is directed to the ball mills (SABC-B circuit). The original grinding circuit at Los Bronces is an example: the pebbles generated in the two SAG mills are crushed in a satellite pebble crushing plant, and then are conveyed to the three ball mills ( Get Price

2020/06/16If there are frequent changes in ore hardness, grinding circuit performance is affected and poses challenges for operators to maintain the target particle size. Further, metallurgical testing has shown that the optimal grind targets can be different for each ore type which proves an additional challenge since the mill feed can consist of either ore type of a Get Price
