The new plant's single kiln for pyroprocessing raw mix into cement clinker will replace the three kilns currently in use at the old plant. (Two of the pieces of equipment date back to the 1960s, and the third kiln was added in 1976.) Total cement output is expected to increase from the present 2,000 tons per day to more than 7,000 tons per day.
