Calculation of the formation process of clinker inside the rotary cement kiln

This study examined the effect of the liquid phase on the heat required for clinker formation and the Coating index, and the relation of the Burning zone temp with the clinker and the heat required for clinker formation. The selection of the liquid phase at 1450 temperatures is beingmaterials difficulty in the Burning, and 1338 is being materials easy in the Burning. All tests and tests were conducted at the Nile Cement Company. The results proved that the more difficult the materials are, the more the Heat required for clinker formation and increase the cost of cement production, and the Coating thickness is weak but strong. The materials easy Burning being little the Heat required for clinker formation and Decreases the cost of cement production, and the Excessive but unstable coating with tendency to form thick ring formation. The found average difference in Heat required for clinker formation between temperature 1338 °C and 1450 °C is 82.26 kJ/kg-clinker representing 2.23% of Total heat input are 3686 kJ/kg-clinker.
