Abstract:

A system for loading predetermined amounts of flowable bulk materials, such as a coal, from a storage area into a conveyance such as a railroad car includes a conveyor for transporting material from the storage area. The conveyor is driven by an adjustable speed drive system while a belt scale provides information as to the weight of material on the conveyor. The conveyor delivers material to a surge bin which feeds it alternately to each of a pair weigh bins. The weigh bins are discharged alternately into the conveyance when a predetermined weight of material has been accumulated in the weigh bin. A programmable controller controls the rate of delivery of material to the surge bin, the loading of each weigh bin and the discharging of material into the conveyance to maintain an efficient throughput of material.
