Furthermore, cement kiln dust may be emitted to control the chemical composition of the clinker. Clinker production is the most energyintensive stage in cement production, accounting for more than 90% of total industry energy use and virtually all the fuel use. The main kiln type used throughout the world is the largecapacity rotary kiln.
