Continental Cement Company’s manufacturing modernization on the banks of the Mississippi River near Hannibal, Missouri, continues to progress on schedule after breaking ground in July of 2006.

The plant has manufactured Portland cement on the Hannibal site for 103 years, beginning operations in 1903 with 16 small kilns producing approximately 300,000 stpy. The plant was previously modernized in 1966, when the original kilns were replaced with a single wet-process kiln. That second reincarnation of the plant increased capacity to 600,000TPY.

The present modernization will completely replace the pyro-processing system with a four-stage preheater/precalciner. A vertical roller mill will replace the raw mill, rock crushing capacity will be doubled with the addition of a new rock crusher and closed-loop screening system and thefinish grinding capacity will be increased with the addition of a roll-press circuitconnecting to one of the existing finish mill. Plant capacity is then expected to be 1.2MM stpy.
