Abstract
A proppant container facilitates the transportation of wet sand for use in a hydraulic fracturing operation. The proppant container is provided with a system for dislodging the wet sand for subsequent use. This may be done by use of a vibrator or an umbrella valve. In another aspect, the proppant container may be used in combination with a rack having a wash system that slurries the proppant for delivery to a blender tub without necessarily resorting to use of a conveyor belt.
