It resulted in more complete combustion of coal and higher system efficiencies. The process of pulverization of coal is carried out in two stages. In the first stage, raw coal is crushed to a size of not more than 15–25 mm. The crushed coal is then transferred to grinding mills, ie, pulverizers, where it is ground to a fine particle size.
3) After that, crushed coal is dried properly before pulverization. The moisture content must be less than 2% after drying operation. 4) Then the coal is crushed again in fine particles in ball mill. This process is referred as pulverization. 5) This pulverized coal is then puffed with air and put into furnace as fluid.
