Even if raw material is brought into the cement plant from a source some distance away, there will still be numerous conveyors throughout the plant. These conveyors usually are driven by electric motors, some of which will be large due to the power required to pull the belts. The larger types have grease nipples that require infrequent greasing.

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.
