Pdf Cement Grinding Optimisation Semantic Scholar

Abstract The current world consumption of cement is about 1.5 billion tonnes per annum and it is increasing at about 1 per annum. The electrical energy consumed in cement production is approximately 110 kWhtonne, and around 40 of this energy is consumed for clinker grinding. There is potential to optimise conventional cement clinker grinding circuits and in the last decade significant ...
