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.
In bowl mill pulveriser raw coal coming from feeder gets ground between the grinding rolls and bull ring segments installed on the revolving Bowl. Bowl is made to rotate at medium speed for proper pulverization of coal. Springs exert necessary pressure on rolls for grinding. Hot air through the mill besides removing coal moisture, picks up the ...
