    Cement kilns are well suited to safely use a variety of fuel sources with their relatively long burning-zone residences times of up to three seconds, high burning-zone temperatures (+1400C) and the alkaline environment that naturally exists in a kiln.The cement kiln - Understanding Cement,However, new cement kilns are of the 'dry process' type. Dry process kilns. In a modern works, the blended material enters the kiln via the pre-heater tower. Here, hot gases from the kiln, and probably the cooled clinker at the far end of the kiln, are used to heat the meal. As a result, the meal is already hot before it enters the kiln.Cement kiln - Wikipedia,Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates. Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant. As the main
