Cement Kilns: Kiln Control

In the cement kiln, rawmix is converted into clinker. The output of the kiln, its running cost (particularly in terms of fuel), and the quality of the clinker product, all depend critically upon the way the kiln is operated. Add to this the formation and breakage of physical barriers in the form of coating rings. A circular argument would
