Energy Use Cement

Energy Use. A cement manufacturing plant requires significant amounts of energy to produce clinker, the main ingredient in cement. Energy in the form of electricity is required to prepare the raw meal (typically limestone, clay, sand and iron ore), run the kiln and, in integrated cement plants, to grind the clinker, gypsum and other materials to produce cement in grinding mills.
