The coal vertical mill adopts the temperature detection device, the online gas analyzer and other explosionproof measures to ensure the safe operation of the equipment. CHAENG has manufactured many coal vertical grinding equipment which have been adopted by a number of Chinese coal grinding production lines. Application. Vertical Grinding Mill (Coal Pulverizer) Explained saVRee,Coal pulverizers are used to dry, grind and classify. Drying is achieved as hot gas passes through the pulverizer and removes moisture from the pulverized coal. The hot gases used should have a low oxygen content, this reduces the likelihood of accidental combustion within the mill. It is possible for hot gases to be taken directly from theCoal Grinding Cement Plant Optimization,Coal Grinding. To achieve good combustion and satisfactory flame formation, coal needs to be dried and ground to a proper degree of dryness and fineness. Drying of moisture in coal is achieved normally by ducting part of the kiln exhaust gas through the mill with inlet temperatures of up to 300°C. Inert kiln exhaust gases with oxygen content
