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.

In the cement industry coal mill fans are used to supply the required air for burning coal and remove the exhaust gases produced after burning. This is where the coal is grinded into the proper size to be fed into the burner. The coal mill fan moves the coal into the grinder. Thus these fans help ineffective burning of coal inside the mill.

A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage [1]) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
