Abstract: Grinding circuit should provide stable particle size distribution while operating in a way to maximize mill efficiency. In this paper, a fuzzy logicbased supervisory control strategy is proposed for controlling product particle size while improving mill efficiency in a ball mill grinding circuit.
Abstract: Regrinding is an essential step in many mineral processing flowsheets as a final preparatory step for mineral separation. It is normally carried out in opencircuit ball mills or rod mills. It is normally carried out in opencircuit ball mills or rod mills.
