The product from the sag mill is further reduced in size using pebble crushers and ball mills hence typical gold or copper ore requires between 20 and 75 kwh per ton of energy to reduce the particle size considering a typical mining operation processes 10000 to 100000 tons per day the energy expenditure in grinding is 50 percent of the

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 70ms and internal mill
