Method is carried out under an atmosphere in the presence of air dioxide carbon or water vapor at temperatures between 800 176c and 900 176c in this research it get the mathematical modeling of the coal activation process in order to predict the behavior of the gas and coal temperature distributioninside a rotary cylindrical kiln
This method is called a semidry process which belongs to the cement dry process production advantages as the dry process is to directly feed raw material powder into the rotary kiln for calcination and the moisture content of raw materials is about 1 2 it saves the heat consumption needed for the moisture evaporation
The cement kiln which is the basic control object of represented work is the most power consumption unit of the cement production the wet production method provides a better quality of output
The essential equipment used in the process are machines such as a balling pan or drum for agglomerating the ore a grate traveling through a furnace and a rotary kiln for transporting the pellets from the grate to a cooler also means are provided to supply hot oxidizing gas to both the furnace and the kiln to heat the pellets
