(All You Need To Know),While grinding the coal, the pulverized coal is taken out of the coal mill from the discharge device by a special induced draft fan. The coarser coal granules will return to the grinding chamber through the return screw of the discharge device for regrinding.Coal Mill - an overview | ScienceDirect Topics,To summarize the coal mill controls, they may be divided basically into two major categories:. 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel.
