How Cement Is Made - Cement Manufacturing Process

The electrical energy consumed in cement production is approximately 110 kWh/tonne, and around 40% of this energy is consumed for clinker grinding. In modern time, the dry grinding circuits for the production of finished cement from cement clinker consist of two-compartment tube mills and the air separators.
