SAG mill/ball mill combinations. The SAG mill (5000 x 2800 mm, 750 KW) reduces the ore to minus 1mm. The SAG mill discharge is cycloned, with a cut 80% less than 75 µm, the underflow passing to a ball mill (4000 x 6000 mm, 1.4 MW), with the cyclone overflow joining the ball mill discharge. The combined ball mill discharge is then cycloned ...
