    To calculate the embodied energy, media use data was obtained for 34 individual mills in addition to 27 comminution circuits. The total comminution energy for these mills was then calculated by combining the total electrical energy and the equivalent embodied energy (assuming forged balls) consumed through media wear (see Figure 1).In relation to the electrical energy consumption, SAG mills

    Feb 16, 2015 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

    A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor. A SAG mill with a 44' (13.4m) diameter and a power of 35 MW (47,000 HP) has been designed. Attrition between grinding balls and ore particles causes grinding of finer particles. SAG mills are characterized by their large
