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 operator then loads materials from the silos into trucks for local deliveries. The terminal can also include bagging, blending or batching into other products. The bulk terminal software supervises inventory, selects the silos to be filled, runs the filling conveyors and monitors progress.
In truck delivery terminals, a truck scale under the silo discharge points connects to the control system. Alternatively, the installers mount the whole silo on load cells to become a legal-for-trade scale. The operator monitors incoming trucks, directs them to one of the silos and manages truck loadout. This proceeds automatically to preset weight limits. 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 truck loadout, each handling 4 silos. Read about it in a World Cement Magazine Editorial.
