Precise Bulk Terminal Controls, Accurate Truck Loadout
Bulk materials such as grain, flour, cement, flyash and fracking sand, used in the extraction of oil and natural gas, are either milled on-site or shipped to the bulk terminals in rail cars and stored in silos. The materials are then loaded into trucks from the silos for local deliveries or bagged, blended or batched into other products. The bulk terminal controls supervise inventory, select the silos to be filled, run the filling conveyors and monitor progress. In truck delivery terminals, a truck scale under the silo discharge points is connected to the control system. The operator monitors incoming trucks, directs them to one of the silos and fills them automatically to preset weights. The Baker-Hughes terminal in Shafter, near Bakersfield CA is typical. This terminal has 12 silos of 610 tons capacity with 3 truck scales for loadout, each handling 4 silos. Read about it in a World Cement Magazine Editorial.
