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. The key economic point here is that optimisation can only begin when the kiln is in control, so kilns that are poorly
