In reference, the mathematical models of static-classifier and dynamic-classifier types of pulverizers were discussed based on the energy and mass balance. Overall, in the research on the modeling of a coal mill system, it is mainly used for the optimal control or the prediction of unknown parameters.
With adequate mill grinding capacity, a vertical mill equipped with a static classifier is capable of producing a coal fineness up to 99.5% or higher <50 mesh and 80% or higher <200 mesh, while one equipped with a dynamic classifier produces coal fineness levels of <100 mesh and 95% <200 mesh, or better.
To summarize the coal mill controls, they may be divided basically into two major categories:. 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel.
