Operating the worlds largest kiln line

The construction is almost complete on the largest single clinker production line in the world. At 12,000 metric tons per day clinker and 4 million metric tons annual cement capacity, this massive greenfield plant was built by Holcim in the United States along the Mississippi River in Ste. Genevieve County, Missouri. The uniqueness of this undertaking is not only the size, but also the strict efficiency goals and environmental regulations that apply to the site development, construction, and operation. Preliminary evaluation of the Ste. Genevieve project began in the late 1990´s, and Holcim ultimately underwent a six year process of reviews and permits involving eight federal and state regulatory agencies. With all permits finally in hand, Holcim awarded a contract in early 2006 to engineering and equipment supplier for all the main and auxiliary mechanical and electrical equipment as well as engineering services, training, and commissioning The focal point of the plant is the single pyroprocess system with new generation clinker cooler and in-line preheater with low NO_x and CO calciner. Furthermore, the supply of four (4) vertical roller mills for cement grinding reinforced this commitment for the most energy efficient solution setting a market standard for finish cement grinding. Because the plant is meeting emission limits among the lowest permitted for any cement plant in the United States and the world, any environmental impact is minimized. In addition, approximately 2200 acres (55% of the total property´s acreage) is preserved in its natural condition for the entire life of the plant. The success of the Ste. Genevieve project was based on the strong partnership and open relationship that has been developed between Holcim and the supplier. Start-up of the plant occurred in August 2009. The kiln and all auxiliary circuits had achieved steady state operation by September 2009 at or above design parameters. With a foundation of a sound technical solu- - tion and combined worldwide resources, this extraordinary project is now a source of pride for all parties involved. The new facility in Ste. Genevieve County is operated by Holcim (US) Inc., a subsidiary of Holcim Ltd. of Switzerland. With majority and minority interests in over 70 countries on all continents, Holcim Ltd. is one of the world´s leading suppliers of cement, as well as aggregates (gravel and sand), concrete and construction-related services.
