In the modern cement plant, the kiln is the most expensive and technically complex part of the plant, and because it must be run all the time (unlike other sections of the plant) it effectively defines the output capacity of the plant. It stands out also in that, unlike the other processes involved, the pyroprocessing stage of cement ...
In 1984, the plant successfully produced Class H Oil Well cement, making it the first flash calciner pyroprocessing facility in the United States to manufacture this product. Before this, all of Centex Corporations Class H oil well cement was manufactured, sold and marketed by the Centex Cement Corporation located in Corpus Christi.
