Coal Handling Safety

Coal and the high temperature inside the mill lead to rapid oxidation of the coal. this results in further heat build-up and the potential for a fire. if the mill is restarted without first removing the hot coal, an explosion can occur when particles are suspended and exposed to the in-rushing combustion air. even in routine mill shutdowns.

Coal Grinding

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.
