Pulverizer - Wikipedia

Similar to the ring and ball mill, the vertical spindle roller mill uses large "tires" to crush the coal. These mills are usually found in utility plants. Raw coal is gravity-fed through a central feed pipe to the grinding table where it flows outwardly by centrifugal action and is ground between the rollers and table.

SEAL AIR BLOWERS - CFW Fans

Seal air blowers eliminate leakage from pressurised air systems, typically in power generation plant coal mills. Dust can enter the mill roller and cause problems where blowers are not used. Guillotine dampers usually require seal air blowers to create a barrier of air at pressures above that of ordinary system operating pressure.

Pulverizer - Wikipedia

Bleeding seal air from plenum chamber to the mill maintains separation between pulverized fuel in the Mill and the outside atmosphere. Inadequacy or absence of seal air will allow escape of pulverized fuel into atmosphere. On the other hand, an excess of seal air leaking into mill will affect the mill outlet temperature.
