Advanced Process Control of grinding & flotation in ...

Usually, the grinding circuit contains at least two interconnected mills with material classifiers (e.g. cyclones) separating the fine material from the coarse (that then goes for regrinding). The process is energy intensive with power consumption of roughly 20 to 30 MW and feed throughputs of 2,500 to 3,000 t/hr. Process variables are mill loads, motor torque and power, plus …
