VG: At best, coal mill safety is not well understood and, at worst, it is ignored. When it comes to coal mill systems, most cement plant operators just presume that the supplier of the equipment knows all of the standards and rules and is capable of making a system that conforms to these and is therefore safe. However, this is not the case.
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, there is a danger that any residual coal left within the mill will oxidise, and may explode as the mill is restarted.
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 ...
