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.
06-10-2010· Dirty airflow measurements are also useful in determining the level of mill performance (mill air in-leakage values—on suction mills), mill heat balance calculations, airflow balance, and the ...
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.
GRMC coal vertical roller mill produced by CHAENG adopts a special structure design and production technology, and the quality is up to the leading level in China. It is the first choice equipment for grinding raw coal and bituminous coal. 1. The raw coal is screened from the raw coal storage yard and then dropped onto the belt conveyor through the grid screen.

We have supplied vertical roller mills (VRM) for raw, coal, slag and cement grinding for several decades. The vertical roller mill is well known in the cement and power plant industries as the preferred mill for grinding of raw materials. It is increasingly used as a solution for efficient grinding.
Almost all the models are based on heat balance where the coal mill body is considered as a lumped thermal mass[1]-[4], so that temperature dynamics cannot be
