seen, the vertical mill consistently presented lower net specific energy consumption than the ball mills which operate on the same circuit. The averages were 11.3, 11.7 and 6.5 kWh/t respectively for ball mill 01, ball mill 02 and vertical mill. Figure 5 – Net specific energy consumption of regrinding circuit.
