Abstract:
A system for controlling silica dust generated during the transfer of frac sand from a storage container through a conveyor system includes a system of conduits having a plurality of inlets for collecting silica dust generated at selected points along the conveyor system. An air system pneumatically coupled to the system of conduits generates a negative pressure at each of the inlets to induce the collection of silica dust at the selected points along the conveyor.
