Embodiments of the present disclosure a system for capturing proppant dust particles when positioned at a fracking operation site including a proppant delivery assembly to receive one or more containers having proppant stored therein. The system dispenses the proppant from the one or more containers and delivers the proppant to other fracking operation equipment. Moreover, the system includes a dust collection assembly positioned proximate and associated with the proppant delivery assembly to capture dust particles released by movement and settling of the proppant when being dispensed and delivered by the proppant delivery assembly. The dust collection assembly is positioned to direct an air flow in a flow path overlying the dust particles to capture the dust particles and move the dust particles away from the proppant thereby reducing risk of dust exposure to fracking operation site personnel.

Method for pneumatically conveying granular material from a supply thereof through a conduit to a plurality of receivers for temporary storage of the material prior to molding or extrusion thereof by drawing vacuum in the conduit using a vacuum pump and controlling the vacuum pump in response to sensed vacuum level in the conduit.

A hot melt system is configured to generate liquid adhesive from solid adhesive pellets. The liquid adhesive is applied to components, such as box tops, to fix components together. A melter is configured to melt the adhesive pellets into the liquid adhesive. Adhesive pellets are periodically fed from a hopper to the melter to maintain a constant supply of liquid adhesive. An adjustable flow restrictor is disposed upstream of a feeder that displaces the adhesive pellets from the hopper to the melter. The adjustable flow restrictor is adjustable to change a flow of the compressed gas flow to the feeder. Adjusting the flow of the compressed gas flow adjusts the feed rate of the adhesive pellets from the hopper to the melter.
