SAG MILL GRINDING DESIGN VERSUS GEOMETALLURGY –

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.

Aug 25, 2014 · In our recent conversation, Prof. Alban Lynch was very sceptical about where semiautogenous grinding (SAG) mills have gone, and thinks they have taken us along the wrong track. He feels that they may be attractive in terms of high productivity, but says that "their energy efficiency is poor, and I feel that these immense machines are going to turn into very large ball mills".
