Background

Coal mills are machines for breaking up and grinding coal briquettes into coal dust, which are important auxiliary equipment for coal dust furnaces. The grinding machine comprises a vertical type flour mill, a high-pressure suspension roller mill, a medium-speed micro-powder mill, an overpressure trapezoidal mill, a Raymond mill and the like. The coal grinding process is a process in which coal is crushed and its surface area is increased continuously. To increase the new surface area, the binding force between solid molecules must be overcome, and thus energy is consumed. The coal is ground into coal powder in a coal mill mainly by three modes of crushing, smashing and grinding. Wherein the energy consumed by the crushing process is the least. The grinding process is most energy intensive. The two or three modes of the various coal mills are combined in the pulverizing process, but the main mode is determined by the type of the coal mill.
