Raw mill exhaust fans or stack fans are also called as de-dusting fans. In cement industry raw mill exhaust fans handle 2.2 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.

Raw mix, high grade limestone, sand and iron ore are transported from their bins to raw mills for drying and further fine grinding. The raw mill is either a Ball mill with two chambers or Vertical roller mill with inbuilt classifier. The hot gases from the pre heater enter the mill and are used for drying material in the mills.
