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 kWh/tonne 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
