It is important to note that the Bond Ball Mill Work Index on SAG ground ore is similar to but not the same as a crushed Bond Ball Mill Work Index. It is 7 higher because the SAG mill grinds the softest components quickly and leaves the harder material to be ground in the ball mill. Figure 3 presents the graph of SAG pinion energy vs. BWi.Discover More
