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

The outlet coal powder flow of the coal mill was proposed as the output control target of the pulverizing system, combined with the compensation of inlet primary air flow of the coal mill. An optimized output control scheme of the pulverizing system was designed on the basis of the estimation of the outlet coal powder flow of the coal mill.

Ball mill. The grinding media is the balls, which may be made of steel ( chrome steel ), stainless steel, ceramic, or rubber. The inner surface of the cylindrical shell is usually lined with an abrasion-resistant material such as manganese steel or rubber. Less wear takes place in rubber lined mills.

3. The primary air flow to the furnace is fed through the mill, with the purpose of heating and lift the coal particles out of the mill and into the furnace. If the the particles are too heavy they will drop to the bottom of the mill and will be pulverized once more. 4. The coal particles are heated to 100 degrees Celsius.
