Grinding aids are organic compounds that are added to the mill during cement grinding. Their main purpose is to reduce the energy required to grind the clinker into a given fineness. In addition, some products (usually referred to as performance enhancers) provide positive effect on cement hydration improving strength development [1].

Ball mills have been used as the main grinding equipment for finished cement production for over 100 years. Although simple to operate and costcompetitive relative to other technologies, the low efficiency of ball milling is one of the main reasons for the development of more efficient grinding processes in recent years.

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.
