Parameters studied include feed size, feed rate, product size, coal hardness and mill energy consumption. The results are presented in a concise manner by combining some of the performance parameters. It is expected that the results are independent of the mill size and can, therefore, be used for scaling to other sizes.

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.
