· This pulverized coal gets sprayed in the combustion chamber with a blow of hot air. The air used to spray the coal into the combustion chamber must get dry before entering the chamber. We call this as "primary air." The extra air required for completion of the combustion is supplied separately, and this additional needed air is secondary air.

The raw coal is then fed into the pulverizer along with air heated to about 650 °F (340 °C) from the boiler. As the coal gets crushed by the rolling action, the hot air dries it and blows out the usable fine coal powder to be used as fuel. The powdered coal from the pulverizer is directly blown to a burner in the boiler.
Calcite Grinding Mill. Calcite grinding mill is suitable for processing medium and low hardness non flammable and explosive brittle materials with 6 or less than 6 grade Mohs hardness, such as calcite, chalk, limestone, carbon black, kaolin, bentonite,
Working principle During cylinder rotation, cascading balls fall down. Coal blocks are pulverized by three forms of motion: impact, extrusion, grinding. Hot air from PAF exchanges heat with pulverized coal and takes them out of air swept mill to storage silo. Advantages Stable operation, reliable performance, easy maintenance.
