PRINCIPLE OF OPERATION. 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 ...
The four most common coal pulverizers types are: BallTube Mills. This type of mill consists of a rotating tube filled with cast alloy balls. Coal is introduced through two hollow trunnions on each side of the tube. As the tube rotates, the balls tumble onto the coal, crushing and pulverizing it. Impact Mills.
the pulverizer throats and matching them for compatibility with the coal pipes and burner nozzle sizes is essential for the best furnace performance. Furthermore, remember that there will be minor variation in mill capacity, fuel quality, and mill inlet airflow rates that must be considered when sizing the pulverizer throat flow area.
