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.

The ideal classifier should therefore have the feature that pulverized coal particles with a diameter of less than 90 μm taken as a qualified product can be separated through the classifier outlet, while particles with a diameter greater than 90 μm were separated into the return pipe and then returned to the mill for regrinding [12].
