A system or method for adding dust control solution to a vertically falling first stream of a substantially dry sand-like particulate material, where the first stream has an effective diameter, the system or method includes a stationary, generally horizontal, deflector plate with a drop-off edge, the plate is mounted into the steam whereby the particulate material collides with the plate and cascades from the plate around the drop-off edge to create a second stream of the particulate material having the general shape of the drop-off edge with a reduced stream thickness and nozzles for spraying dust control solution into the second stream, which system or method is preferably for rapid transportation to the site for using the sand-like particular material.

A system for adding dust control solution to a vertically falling first stream of a substantially dry particulate proppant, where the first stream has effective diameter, the system including a stationary, generally horizontal, deflector plate with drop-off edge, the plate mounted into the stream whereby the proppant collides with the plate and cascades from the plate around the drop-off edge to create a second stream of the particulate proppant having the general shape of the drop-off edge with a stream thickness and nozzles for spraying dust control solution into the second stream.

Methods including placing particles that are substantially dry in a hopper; conveying the particles from the hopper via a conveyance to an open-air gap; adding a fluid to the particles in the hopper, the particles in the conveyance, or both, thereby reducing an amount of a dust produced at the open-air gap. The particles may be sand, silica, gravel, bauxite, ceramic materials, glass materials, polymer materials, polytetrafluoroethylene materials, nut shell pieces, cured resinous particulates comprising nut shell pieces, seed shell pieces, cured resinous particulates comprising seed shell pieces, fruit pit pieces, cured resinous particulates comprising fruit pit pieces, wood, composite particulates, and combinations thereof.

The present invention relates to a dust suppression system for use in a container, and a misting apparatus therefor. In one form, the dust suppression system comprises at least one misting apparatus for contributing to the creation of a mist layer for preventing the escape of the dust from the container, the misting apparatus comprising a means for generating an airflow, and a means for producing a mist in the airflow so that the mist is carried by the airflow.

A sprinkler system for a temporary chute used for disposal of construction materials during a construction or renovation project. The sprinkler system is releasably engaged with the temporary chute and is used to control dust within the chute, wash down the chute, and extinguish fires. A housing of the sprinkler system is releasably engaged with an intake hopper of the chute, placing an interior chamber of the housing in fluid communication with the chutes' tunnel. First and second sprinkler heads are located within the interior chamber. The first sprinkler head is temperature sensitive and automatically actuated when a threshold temperature is crossed. The second sprinkler head is manually activated by an operator to spray liquid into the tunnel to control dust or wash the interior surfaces of the chute. The sprinkler system and temporary chute are disengaged from the building once the construction or renovation project is completed.

A spout assembly and related method of regulating the flow of particulate material. The spout assembly includes a chute, at least first and second plates, and a counterbalance mechanism. The first and second plates are positioned downstream from the chute, the lower ends of the first and second plates defining an opening with an area that is smaller than a cross-sectional area of the chute so that the material may accumulate prior to passing through the opening. The counterbalance mechanism produces a biasing force on the first and second plates toward the centerline to adjust the area of the opening, and permits the first and second plates to move outwardly away from the centerline in response to the weight of the accumulated material. The counterbalance mechanism includes at least a first separately adjustable counterbalance coupled to the first plate and a second separately adjustable counterbalance coupled to a second plate.

Systems and methods for silica dust reduction at well sites are described herein. The system can include a blower, a transfer hose having a first end connected to the blower, a second end connected to a hopper containing a granular material, and an interior volume. The system can also include a supply of dust suppression solution in fluid communication with the interior volume of the transfer hose.
