Optimization of mill performance by using. The pulp density is an important parameter which influences the grinding efficiency. In iron ore, for instance, a variation of 2 to 3% solid content in the slurry could lead to a difference up to 10% on the energy (kWh/T) for a similar grind. Optimization of mill performance by .

with such an effect. Softer ore would require mill speed decrease to maintain a satisfactory ore bed and grinding conditions, while protecting the mill liners from direct impact. Conversely for hard ore, mill speed is increased to input more energy to the process and improve the tumbling action to deliver the required grind. Operation

The nominal mill efficiency, at optimum speed, is 80 Mg/h. The dimensions and the high mass of the rotating elements cause the drive system to be overloaded when the mill filled with copper ore is started. For this reason, the mill is stopped only in the case of a failure or planned maintenance work. The
