Process Of Operating A Cement Mill

Advanced Process Control For The Cement Industry

Controlling a cement kiln has always been a challenging task for cement plant operators. These days, a computer-based pyro control system is not merely nice to have, it is a practical necessity. Both the inherent complexity of the pyro process and the far-reaching consequences of off-spec clinker, faulty operating conditions and production ...Controlling a cement kiln has always been a challenging task for cement plant operators. These days, a computer-based pyro control system is not merely nice to have, it is a practical necessity.The milling process generates heat and excessive mill temperatures are undesirable. It is clearly helpful, therefore, if the clinker is cool as it enters the mill.Cement manufacturing components of a cement plant.
