The consumption of the energy in the cement plant is mainly due to raw mill, cooler, preheater and rotary kiln [14]. The total energy loss of the plant is generally accounted for about 3539% of the total energy input [15]. This energy loss is due to the loss from the exhaust gas, cooler and the radiation heat transfer from the kiln cell.
