Mathematical model and control of a coal pulverizer
Abstract. A physical model of a roll and race coal pulverizer is developed. The processes of grinding, pneumatic transport, drying, and classification of a Babcock and Wilcox MPS-89 mill are modeled based on the fundamental physical laws. Roller pressure, coal-particle strength, and the Gaudin and Meloy function are used to predict the coal ...
