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.

Coal found in sedimentary rock, is crushed into the appropriate size and used as fuel for electricity generation or the iron-making process. Lumps of coal can be used directly as a fuel. However some coal is first washed to make it into 'high grade coal'. It can also be sorted into various sizes, depending on what the fuel is required for.
