A proppant delivery assembly receives and supports a plurality of containers having proppant stored therein. A cradle has a top surface which receives and supports the plurality of containers when positioned thereon. The cradle enables the plurality of containers to dispense the proppant stored therein. A proppant mover is positioned to underlie and extend along the top surface of the cradle aligned with the plurality of containers to receive proppant from the plurality of containers. The proppant mover carries proppant away from the plurality of containers. A chute is coupled to the cradle for receiving proppant from the proppant mover and directing the proppant to a blender hopper. A hood assembly is disposed at an end of the chute opposite the proppant mover for directing a vacuum air flow that removes a volume of air containing proppant dust particles directed from the chute. The hood assembly includes a curtain extending about a perimeter of the hood assembly and downward therefrom to at least partially define the volume of air being removed by the hood assembly.

A receiver having a horizontally elongated chamber within a housing, the chamber having a convex triangular cross-section and a dump flap defining a bottom vertex of the triangular cross-section, with a horizontal air/vacuum resin material inlet connecting to the chamber, and a horizontal air/vacuum outlet leading from and connected to the chamber.

Disclosed is a system for transferring fuel pellets from one container which may be at a location external to a building to a second container which may be at a location in an interior of the building. The system may include a first container positioned at a location remote from the building and a second container positioned proximate to the building. The first and second containers are connected to one another to permit the transfer of fuel pellets from the first container to the second container by a pneumatic apparatus.

An example of an apparatus to transfer additive manufacturing build material from a container is disclosed. The example disclosed herein comprises a holding structure and a conduit. The holding structure comprises a fixation element to physically attach the holding structure to one or multiple sides of the container. The conduit may be couplable to a vacuum system through a vacuum open end to extract the build material. The holding structure receives and positions the conduit substantially vertically such that a build material extraction open end of the conduit is positioned towards the base of the container. The vacuum open end and the build material extraction open end are opposite open ends from the conduit.

A material conveying system, comprising: one or more material sources for providing material to be transferred; one or more destination locations for receiving material from the one or more material sources; one or more material conveying lines; one or more vacuum pumps wherein each vacuum pump is operatively connected to one or more of the one or more destination locations via one or more vacuum source lines; a sensor disposed on, in or near each of the one or more material conveying lines; a programmable electronic control unit (ECU) connected, via wires or wirelessly, to each component of the material conveying system including the one or more material sources, the one or more destination locations, the one or more vacuum pumps and to the one or more sensors; wherein the ECU uses data from the one or more sensors to (i) determine flow patterns and/or stream density of the material being conveyed through the one or more material conveying lines; and (ii) make automatic adjustments for optimizing and maintaining the material flow patterns in the one or more material conveying lines based on data provided by the one or more sensors.
