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 ...

Vertical Roller Mill Cement Raw Material Grinding. Raw Material Drying-Grinding - Cement Plant Optimization. Vertical roller mills can typically handle an aggregate moisture of up to 20 in raw materials and consumes about 30 less power in grinding. Hence it is commonly preferred for grinding operation in new plants of higher capacities.
