Coal Oil Mixture - an overview | ScienceDirect Topics
The vast majority of coal mill designs are based upon a 50 to 55 HGI design point. However, grindability is a complex issue and such factors as coal moisture content, required fineness (high volatile coals can require a coarser grind) along with the milling and burner systems are all factors in assessing coal grindability.

The BTM is a low-speed mill that primarily grinds coal by impact and attrition. The VRM is a medium- speed mill that grinds coal by compression and, because of the low coal inventory in the mill and flat grinding surfaces, develops shearing action as well. For both mills a constant centrifugal force is maintained. The speed
