The layout of the coal mill with a rotary classifier. Download
Vertical Coal Mill (VCM) is equipment for grinding and pulverizing coal into micron size. Rotary kilns then use the powders as fuel burners. The VCM has a housing section equipped with a liningIn a vertical coal mill, coal is often ground at the bottom of the classifier and then the pulverized coal particles are blown up to the rotating impeller mounted at the top. So far, most of the experimental measurements and numerical simulations have been conducted only at a given inlet condition of the incoming two-phase flow from the bottom Classification performance of model coal mill classifiers with

Decomposition-Based Bayesian Network Structure Learning
In the structure learning of the large-scale Bayesian network (BN) model for the coal mill process, taking the view of the problem that the decomposition-based method cannot guarantee the sufficient learning of abnormal state node neighborhood in the diagnosis model, this paper proposes a new BN structure learning method based on Abstract. The paper presents development and validation of a coal mill model to be used for improved mill control, which may lead to a better load following capability of power plants fired by pulverized coal. The model is relatively simple, yet it captures all significant mill dynamics. The model is validated using data from four mills of Derivation and validation of a coal mill model for control
