Cement production is a highly energyintensive process. Cement making consists of three major process steps: raw material preparation, clinker making in the kiln, and cement making. Raw material preparation and cement making are the main electricityconsuming processes, whereas the clinker kiln uses nearly all of the fuel in a typical cement plant.
