use use of coal mill in steel plant

Coal Mill - an overview | ScienceDirect Topics

In China and India in particular, coastal power stations tend to mill coal more finely, use superior emissions to control technologies, and have a tendency to use higher-quality coal blends. The result is higher quality and greater consistency in fly ash chemical and physical properties, to the extent that the material is more desirable to ...
