Coal Mill In Cement Process

In a cement plant two systems of coal firing are used, namely, a Direct firing and b Indirect firing. In direct firing system, coal is milled on line and is directly fed to the kiln. The primary air is used to dry the coal. High moisture coal is not suitable for direct firing, as this has the effect of lowering the flame temperature and therefore the process efficiency.
