PLANT PROFILE Mississippi Lime, a sprawling limestoneprocessing operation south of St. Louis, has entered the world of reliability with flying colors. TOM FRENCH, SITE RELIABILITY process leader at Mississippi Lime in Ste. Genevieve, MO, is getting more sleep these days. It's a small pleasure that he counts among many other positive results to emerge from a multi-year, multi-faceted, reliability-improvement process he and his team helped put in place at this limestoneprocessing operation. Located 65 mi. south of St. Louis along the Mississippi River and perched over what is considered the largest limestone deposit in North America, the privately held company mines, crushes, and processes limestone onsite. It makes a variety of calcium-based products (see sidebar) and bags or bulk-loads them for distribution. The multi-shift, year-round operation is the town's largest employer and is celebrating its 108th year in business. With headquarters in St. Louis and facilities in several other states, Mississippi Lime is one of the nation's top lime producers. At the plant's newer horizontal kilns, heating occurs within pre-heaters, then stone enters the tubes which rotate and are angled at a 2-deg. pitch to move heated stone to the next operation.
