Abstract: 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.

Abstract: 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.
