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.

The invention relates to a feed delivery device with at least two feed containers and a device for delivering, mixing and distributing feed. The mixing device and the distributing device are formed separately from each other and are movable relative to each other for assuming a transfer position in a transfer station, where the mixing device has a movement.

A frame support includes an extensible carrier having a free end, a guide configured to guide the extensible carrier in an axially-movable manner, and a vertical support unit. The vertical support unit is arranged eccentrically at the free end of the extensible carrier. The frame support is adapted to be coupled to a vehicle.

A vacuum tank with a rear door, and air and material hoses connectable to the tank door. The tank is rotatable, while the door remains stationary. Liquid, particulate, or slurry material can be vacuumed into the rotating tank, without twisting the hoses. Additional water and/or drying agent can be added to the tank to create a slurry mixture, which can then be discharged from the tank at a convenient dump or work site. The tank may be mounted on a truck, trailer, or frame for transport to a job site and the dump or work site. In an alternative embodiment, the tank may be tilted end-to-end between fill and discharge positions.

Mixing systems that include a mixer housing and a plurality of roller assemblies for mixing and processing materials is disclosed. Each roller assembly includes a roller that extends between sidewalls in the mixer housing and rotates to mix an additive into the material and to carry agglomerated solids toward a discharge of the mixing system. Each of the rollers may have a protrusion geometry formed in the outer contact surface, where each protrusion geometry is complementary to an adjacent roller.
