DSS055: Coal Mill Safety In Cement Production Industries

Power generation typically involves direct firing systems. There is an air swept mill with direct pneumatic conveying through to the burners. The risk of explosions is more or less reduced to an explosion inside the mill, which therefore needs to be explosion, pressure, and shock-resistant. NFPA requires coal mills to be good for 50 PSI.
