The finished product exits the plant by means of a 30-inch variable speed hydrostatic discharge belt. Belt speed is computer controlled to maintain the optimum material load for increased scale accuracy. The conveyor is precision aligned, meticulously maintained and is equipped with several forms of cleaning devices to ensure accurate zero and calibration of the scale. Material then enters the 1.5 cubic yard gob hopper, which is utilized to prevent material segregation and to interrupt the continuous flow of product allowing trucks to enter and exit the loading area. The gob hopper may be left open continuously so that a conveyor may be used to remove the finished product from the plant.
