Ball and Race Mill ~ ME Mechanical

07-07-2017  The moving balls and races catch coal between them to crush it into a fine powder. For crushing of coal, the force needed is applied with the help of springs. The hot air supplied picks up the coal dust as it flows between the balls and races; then enters the classifier. Oversized coal particles are returned for grinding. The coal particles of required dimension are discharged from the top of the

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
