desired fineness of the coal mill
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. Generally, a value of ...

Reduced Unit Capacity
Less than optimum fineness also causes poor distribution of coal between burner lines which will influence air flow distribution. Taking this into account, coal fineness must be maintained at >75% passing 200 Mesh and <0.5% remaining on 50 Mesh. More even fuel distribution is always achieved with higher coal fineness.
