The present disclosure relates to a pouch conveying system for routing one or more pouches. Each pouch may include at least one self-closing frame attached to an end of a pouch body. The self-closing frame has a first frame section having at least two portions coupled to each other through a first joint, and a second frame section having at least two portions coupled to each other through a second joint. The second frame section coupled to the first frame section at a first end by a first coupler and at a second end by a second coupler, such that at least one of the first coupler and the second coupler move inward, flexing the first frame section and the second frame section about the first joint and the second joint.

A proppant container facilitates the transportation of wet sand for use in a hydraulic fracturing operation. A metering conveyor is positioned between a blender tub and a proppant motive mechanism, such as a conveyor or wash system that receives discharge direct from proppant containers of the type normally used to transport sand in support of a hydraulic fracturing operation. The metering conveyor is fitted with sensors and/or a knife-edge gate that may be used to facilitate flow control operations.
