Early cage mill crushers were used principally to crush materials that were not particularly abrasive – corn, salt, coal, clay kaolin. By 1900 Stedman's range of multi-cage mills and pulverizers includes the H-Series, F-Series for sticky, high moisture and Y-Series designed for less abrasive material appliions. In general

This is indiive of how important pulverizers are to the successful operation of a power plant. Mill Capacity. The ability of a power plant to pulverize coal for combustion is directly related to the load produced and indirectly impacts other areas such as slagging, ash sales and opacity.

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

Impact of Pulverizer Performance on Nitrous Oxide Emissions. A coal fired boiler generates three types of Nitrous Oxides. Thermal NOx. Approximately 20% of the NOx produced. It is formed from Nitrogen in combustion air. Atmospheric air utilized to provide combustion air for a coal flame is ~20.9% O2 and 78% N2.

Pulverizers have three functions, pulverization, drying and classifiion. The classifiion function plays the important role of ensuring that only fine particles of the pulverized coal are sent to the boiler. Within a rotating-type classifier, fine particles are passed through while coarse particles are eliminated by utilizing the
