The coal classifier is highlighted in the green colour as shown in Fig. 3 between the multi-dimensional geometry of the coal mill and the 3-D view of the meshing grid. This is to highlight that the flow of gas-particle mixture (ground coal and air) is meshed and modelled. This to tackle the coal particles being separated by the coal classifier.

2. The hot air is used for transportation of the recirculating coal within the mill and also for transporting the coal from the pulverizer to the furnace. As the coal is continuously reduced in size, the smaller/lighter particles are swept from the bowl by the hot air. Hot air (and cool tempering air) is provided by the primary air fans.
