Electrical energy accounts for up to 20% of the energy consumption of a cement plant. Electricity consumption varies from 90 to 150 kWh / t of cement, while a wet process is much more energy intensive than a semi-wet or dry process. Electricity consumption also depends on the nature of the product and the degree of grinding.
