Grinding energy was approximately 50 per cent of the ball mill and the drying capabilities allowed direct processing of materials of up to 20 per cent moisture content. The main energy issue was the high power consumption of mill fans, with pressure drops of 100mbar not uncommon with high nozzle ring velocities (>70m/s) and internal mill circulating loads of >1000 per cent. Manufacturers have

SAG milling, the most widely used and energy consumer stage in the grinding circuit, acquires a very important role. Usually, tumbling mills power equations have been derivate from mechanics as the product of torque and rotational speed. Models for the prediction of the power drawn by ball, semi-autog-enous and fully autogenous mills have been developed and cited in the technical literature
