The four most common types of coal pulverizers are Ball-Tube 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 ball mill is a slow speed mill and has two primary areas where coal pockets can exist and create fires the inlet outlet ductwork and the classifier. In a ball mill the
Pulverized Coal Preparation System. 1.The raw coal from storage and conveying system come into air swept coal mill for grinding. The coal powder mass and heat transfer with 200350 hot air. The moisture enter into flue gas from coal. Coal powder is dried by hot air. Then coal powder come to powder separator with airflow for classification.
Constant speed rotation of mill disc will distribute materiao evenly in the lining plate of mill disc. There inclined mill roller will be bite material and pulverize. Grind material with the function of pressure and friction. Centrifugal force will make pulverized material at

In the ball-and-race mill Fig. 13.3, balls are held between two races, much like a large ball bearing.The top race or grinding ring remains stationary while the bottom race rotates. As the coal is ground between large diameter balls and the ring, the balls are free to rotate on all axes and therefore remain spherical.
