Dry Kilns with Multistage Pre-heaters and Pre-calcination Whenever economically feasible a wet process kiln can be converted to a state-of-the art dry process production facility that includes either a multi-stage preheater, or a multi-stage pre-heater and a pre-calciner.
Cement manufacture is considered also an industry of intense CO2 emission. CO2 evolves from fuel combustion and from decomposition of carbonates which usually represent the major fraction of the clinker raw mix. Cement production accounts for about 8 % of total CO2 emission from all human activities (IEA GHG R&D, 1999).
Occupational health and safety has top priority within the cement industry. Hot areas and cyclone-preheaters in particular are among the most dangerous places in a cement plant. Dealing with hot meal can especially be a potential source of severe injury. Special attention therefore has to be directed towards working safely in these areas.

Higher SO 2 emissions by rotary kiln systems in the cement industry are often attributable to the sulfides contained in the raw material, which become oxidised to form SO 2 at the temperatures between 370 °C and 420 °C prevailing in the kiln preheater.
Preheater Used in Rotary Kiln. For cement production line, there are many cement equipments among which cement preheater is included. Rotary kiln is used widely in cement plant, and we design and produce new-style rotary kiln with vertical preheater which takes use of the heat of the flue gas coming out from the kiln end to preheat the dolomite to 800℃ in the preheater.
