Vertical Coal Mill Heat Balance

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.
We have 40 years of experience in mechanical manufacturing and provide you with the most sophisticated equipments.
