A conveyor sled assembly is utilized to supply proppant in support of oilfield hydraulic fracturing operations. The conveyor sled assembly includes precisely positioned components where tolerances between components are so small as to prevent significant spillage at component junction boundaries. This manner of fitting proppant pods onto the conveyor sled assembly increases predictability of which pods will discharge their proppant load first. This enhances reliability of the overall proppant delivery system.

A loading apparatus for a granular material conveyor system having a conveyor belt is described. The apparatus has a chute assembly mounted to a frame over the conveyor belt and having an adjustment mechanism and a positional lock assembly connected to the chute assembly and the frame for adjusting an upper surface of the chute assembly to a desired angle within a range of possible angles. One or more side deflector panels are mounted to the frame over the conveyor belt and an adjusting rod assembly connects the deflector panels to the frame for adjusting an angle of the deflector panels.

A bulk material transport system includes one or more bulk material transport bins, weighing platforms, and vehicles arranged in various combinations as bulk material transporters, assemblies, and units. The system is useful for coupling with a bulk material container, forming a reduced pressure region at an inlet of the transport bin, and dispensing bulk material into the transport bin through the reduced pressure region.
