Read OnThe Ramla cement plant (see Fig. 1 for an aerial photo of the plant) has been in operation for 46 years. The original process at the Ramla cement plant to produce cement from limestone, which is the base material of cement, was a so-called wet line process. The original wet line had a capacity of 1,800 TPD (Tons Per Day).
Read OnRaw Mill Exhaust Fans. 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 ...
