The present invention proposes a relief module comprising a tubular body (10) for the passage of bulk material, at least a lateral opening (12) in the tubular body (10), a window (20) to cover the respective lateral opening (12), the window (20) operating in a closed position preventing the bulk material from exiting through the lateral opening (12) or in an open position allowing the material to exit through the lateral opening (12), the window (20) having at least one portion made of filtering material allowing the air to pass through and retain solid particles, when the window (20) is in the closed position. The present invention also proposes a bulk material discharge device which receives the bulk material from a feeding system and discharges the bulk material to a destination, the discharge device comprising a relief module configured according to the invention.

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.

Embodiments of methods and systems of transferring proppant for fracking to reduce risk of production and release of silica dust at a well site are provided. An embodiment of a method can include positioning a plurality of containers each having proppant for fracking contained therein onto a conveyor at a well site, downwardly discharging proppant from each respective container of the plurality of containers, funneling proppant from the one or more outlets of each of the plurality of containers through a plurality of conveyor hoppers, receiving proppant onto the conveyor belt, conveying proppant on the conveyor to a chute, and depositing the proppant into the chute for use in a blender or other location at the well site.
