total specific energy consumption of the comminution system is 20 to 50 % less compared to conventional ball mills. The double rolls used for the process are on the first glance similar in design to conventional crushing, compacting or briquetting rolls but differ considerably in details, particularly in view of the very high separating force.

specific energy values demonstrated contrary evidence to Herbst and Furstenau (1973). The results indicated that 3 specific energy is not independent of ball load, and that an increase in ball load from 25% to 40% of the mill filling . would increase the specific grinding energy 8% while the capacity increased by 16%.

The Bond equation is used to calculate ball mill specific energy from T 80 to the final product P 80 size. The total circuit specific energy is the sum of the SAG mill and ball mill specific energies. W SAG = R.(Ms+16000)/(Ms.447.3) (4) W T = K a.K b.W SAG.[10.BWi.(T 80-0.5-1700-0.5).EF5] + W BM.K BM (5) Where: W SAG = SAG mill specific energy from F 80 152 mm to T
