Coal Pulverizer – Power Plant

2022 7 13   The four most common coal pulverizers types 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.
