Dec 18, 2017 . The cement sub-sector consumes approximately 12–15% of total industrial energy use. Therefore, a state of art review on the energy . Based on the factory's technology, the specific consumption of electrical energy for 1 ton of cement is around 110–120 kWh[16]. The electrical energy that cement factory.

Energy Efficiency and Saving in the Cement Industry .

The production of cement clinker from line and chalk by heating line to temperatures above 950°C is the main energy consuming process. Portland cement, the most widely used cement type, contains 95% cement clinker. Large amounts of electricity are used grinding the raw materials and finished cement.
