the feed are wasted. As a result, the mill unit operating cost increases directly by the amount of the dilution factor. For example in a project whose processing cost has been estimated at $18/t,a 10% dilution means $1.80is spent processing waste in the mill for every tonne of feed. For a 30,000 tonne a

The focus of research in control of coal mills has not been addressed on moisture estimation. Instead, dynamic modeling and nominal control of these coal mills have been the topic of numerous of publications. Some examples dealing with modeling of coal mills are (Rees and Fan 2003), (Zhang et al. 2002) and (Tigges et al. 1998).
In this paper an observer-based method for detecting faults and estimating moisture content in the coal in coal mills is presented. Handling of faults and operation under special conditions, such as high moisture content in the coal, are of growing importance due to the increasing requirements to the general performance of power plants.

Abstract: The paper presents development and validation of coal mill model (including the action of classifier) to be used for improved coal mill control. The model is developed by using the mass and heat balance equations of the coal mill. Genetic Algorithm is used to estimate the unknown parameters that are used in the model validation.
