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

A Comparison of Three Types of Coal Pulverizers

Ball Tube Mill The Ball Tube Mill (BTM) is a cylindrical low-speed grinding mill. It consists of a steel barrel, lined with cast abrasion-resistant liners and partially filled with hardened steel balls. Coal and pre-heated primary air enter one or both ends of the mill from a crusher/dryer or feeder. As the mill rotates, the balls cascade and
