Combustion Engineering, Babcock & Wilcox, and Riley Stoker Corp. are major manufacturers of coal pulverizing equipment. 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.

Pulverized coal (pulverized fuel-pf) has been fired in rotary cement kilns (see Kilns) and boiler furnaces (see Boilers).The latter are basically boxes lined with tubes in which water is evaporated and contain a water/steam mixture. The coal is pulverized to a fine powder, usually so that 70% is less than about 75 μm in size, before being carried by part of the combustion air stream to the ...

The history of pulverization date back as early as 1824 and was envisaged by Carnot in a coal fired engine. In 1890 Diesel made use of pulverized coal in his diesel engine. The pulverized coal firing was first developed in cement industry which then migrated to power and process industries. Pulverizing coal in boiler is an important factor the overall cycle efficiency.
