Synthetic (FGD) Gypsum Handling System

The objective of installing this system was to lower the production cost of cement by replacing the high cost natural gypsum with the lower cost synthetic [Flue Gas Desulfurization (FGD)] gypsum.

The plant operates two cement mill systems. The system installed includes two dump hoppers each equipped with two drag flight feeders. Gypsum from each dump hopper is metered onto a collecting belt conveyor equipped with a weigh idler. The collecting belt conveyor discharges onto a belt conveyor that discharges the gypsum into the cement mill inlet chute.
