The coal mill is a vertical roller mill, in which the coal particles are collected in a bag filter through a grit separator. The required size of coal is 80% of 90 μm and less than 2% of 212 μm (Atmaca and Yumrutaş, 2014). Hot air generated in a coalfired furnace or from a cooler/preheater is used for drying the coal in the mill.
