Review of control and fault diagnosis methods applied to coal mills
Coal mills or pulverizers play a very essential part in the coal-fired power production system. Coal mills grind the coal into fine powder, and the primary air entering the mill dries and drives the coal into the power plant furnace for combustion. Coal mills are categorized based on the speed into three categories namely, low speed, medium1 Potential safety hazards in the coal mill system. 1.1 Spontaneous combustion occurs. The process of cement production determines the need to use a large amount of coal. The use of coal is mostlyDISCUSSION ON SAFETY PRODUCTION OF COAL MILLING

Analysis of the Coal Milling Operations to the Boiler
Primary air is admitted through the mill, which carries the finest coal particles to mill outlet. The air and coal mixture passes through a classifier, located at the upper part of the mill, where an additional particle separation takes place. Coarser particles return to the coal chute and fine particles are carried to the classifier outlet.mill翻译：磨坊，碾磨厂，磨粉厂, 碾磨机，磨粉机, 制造厂，工厂, 磨；碾碎, 铣（金属）。了解更多。 The equations were calibrated and validated with 116 and 45 samples, respectively, for flotation index and with 149 and 176 samples, respectively, for milling tests.mill中文(简体)翻译：剑桥词典 Cambridge Dictionary
