Coal mills use static or dynamic pneumatic classifiers to select the correct cut size and consistency for combustion. For coal, the industry standard cut size for a classifier is that 75% of coal delivered to the burner must pass a 200 mesh screen (75 μm) [6], and for biomass the standard classifier setting is 1 mm [7].

The BTM is a lowspeed 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

The operation of the millclassifier system (Fig. 2) that was considered in this study is described in the following steps: the coal enters the pulverizer with 925 °C gas (1) withdrawn from the boiler. Then, the beater hammers (2) break the coal into smaller pieces, and the coal drying process begins.
