Rotary kilns of the cement industry and classic incineration plants mainly differ in terms of the combustion conditions prevailing during clinker burning. Kiln feed and rotary kiln exhaust gases are conveyed in counter-flow and mixed thoroughly.
A modern cement kiln is a rotary kiln, set upon piers across its length. The kiln, installed at a slight pitch, is rotated slowly transporting the material the length of the kiln. Over the years, the standard configuration of the kiln used has evolved with advancements in the process, lowering overall energy
Rotary kiln (cement kiln) is used for making of cement clinker and there are dry and wet methods to make cement. Rotary kiln (metallurgy chemical) kiln is used for magnetic roasting of iron ore and oxidizing roasting of chrome and nickel in the steel factory.
Preheating Zone/Kiln Inlet Zone. The first reaction zone of rotary kiln system is known as the preheating zone. Here the charge gets heated up to about 800℃ before entering the calcining zone. Bricks in this area are prone to chemical attack from gases containing alkali and sulphur.
Rotary cement kilns can be classified into wet-process kilns, semi-dry kilns, dry kilns, preheater kilns, and precalciner kilns. The pertinent process chemistry and the heat requirements that drive them so as to be consistent with the transport phenomena theme are shown.
