The gas flow and drying capacity was normally decreased with mill size (grinding capacity). In other mills like vertical roller mills both grinding and drying take place together inside the mill by the hot gases supplied through the mill. The vertical roller mills are usually designed to have a rather constant ratio between airflow and grinding ...
R90>=1/2. Volatile Content %. Coal Moisture: The degree of drying, and therefore the required mill outlet temperature (from 6580 0 C) will depend upon the type of coal ground.

The increase in milling capacity in turn would enable a reduction in the amount of coal used without the requirement for supplementary grinding facility. This paper presents an experimental investigation of the cogrinding behavior of coal and biocarbon produced by pyrolysis of woody biomass from two different conditions and postprocesses.
5. Conclusions. Determining the properties of coal, in particular, the grindability, is of great importance because coal graining plays a huge role in each use of coal: combustion, gasification, enrichment and pyrolysis. The energy consumption for breaking up (grinding) coal is significant and amounts to 515 kWh/t.
