Monitoring on individual compartment outlets provides data to ...
Raw mill exhaust fans or stack fans are also called as dedusting fans. In cement industry raw mill exhaust fans handle ton of exhaust gases for the production of 1 ton of clinker. Raw mill exhaust fans are operated with very adverse situations because the fan handles mainly gases such as CO2, N2, NOx and Sox along with some dust particles.
The energy efficiency of dry ballmill grinding of cement depends on factors such as ball charge fillratio, mill length/diameter ratio, size distribution of the ball charge, operating conditions of the air separators, air flow through the mill, production rate, use of grinding aids, and the hardness and fineness of the feed and product ...
