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 100% capable of making a system that conforms to these and is therefore safe. However, this is not the case.

The transport air that carries the coal from the mill to the burners is a small fraction of the total combustion air. It is kept at low temperature, limited to about 373 K, for reasons of safety against ignition and explosion in the mill and in the powdered coal transport pipeline between the mill and the burners.
