Improving Coal Pulverizer Performance and Reliability

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 Grinding Action is carried out by aseries of
