Holcim’s US cement plant in Ste. Genevieve, Missouri produces four million metric tons of clinker every year, and its emission limits are among the world’s lowest. FLSmidth designed the plant and acted as a complete one-source supplier of engineering services, project management, and all the major machines and auxiliary equipment.
The focal point of the plant is the pyroprocessing system with a Multi-Movable Cross-Bar® Cooler that is 23 grates wide by 123 grates long and has a seven-row CIS-MFR fixed inlet and a six-roll Heavy Duty Roll Breaker at the cooler discharge. Additionally, there is a dual-string, “hybrid” Low-NOx In-Line Calciner (ILC) preheater; a DUOFLEX® Burner designed for firing coal, petcoke, waste oil and solid AFR; and a three-support rotary kiln that is 6.6 meters diameter by 93 meters long. The clinker is grinded in four OK Cement Mills.
