This paper presents a coal mill model that considers the effect of coal moisture on its accuracy. This mathematical model is derived through the analysis of mass flow, heat exchange, and energy transferring balances in which all heat input into or output from the coal mill are calculated quantitatively to reduce the number of unknown parameters that need to be identified.

Abstract: Considering the shortage of industrial process data, process monitoring model based on data statistics is difficultly established, resulting in an adverse impact on the accuracy and timeliness of monitoring. Transfer learning provides an effective way for the above situation. In view of the fact that the coal mill process data in the target domain is less, on the basis of the ...

Coal mill is also called coal pulverizer or coal grinder. It is a mechanical device used to grind raw coal into pulverized coal powders. The most used coal mills in cement plants are air-swept ball mill and vertical roller mill.. At present, most cement plants use coal as the main fuel in the clinker production process.
