A proppant discharge system includes a container having an outlet formed at a bottom thereof, a gate affixed at the outlet and positioned on the floor of the container so as to be movable between a first position covering the outlet to a second position opening the outlet, a support structure having the container positioned on the top surface thereof. The support structure has at least one actuator affixed thereto. The actuator is positioned so as to move the gate between the first position and the second position. The container has a cage affixed on the floor thereof in a position over the outlet. The gate is positioned within the cage and is movable by the actuator so as to open the gate so as to allow proppant to be discharged therefrom.

1. A process for providing fracking proppant to a well site, the process comprising: delivering the proppant to a loading station, the proppant having a substantially round, spherical shape and a tightly-graded particle distribution;providing a plurality of proppant containers, each of the plurality of proppant containers comprising: lateral sidewalls,a top,a bottom distal from the top,an outlet in the bottom,ramps extending upwardly at an angle from the bottom toward the lateral sidewalls and each ramp of the ramps terminating at a portion lower than a vertical extent of the lateral sidewalls, the ramps positioned to funnel the proppant toward the outlet along substantially smooth, planar surfaces and being surrounded by the sidewalls extending to the bottom;an inner volume defined by the top, bottom and lateral sidewalls enclosing the ramps within the inner volume, anda gate adjacent the outlet, the gate being moveable between an open position and a closed position to enable the proppant to flow out of the inner volume;loading each of the plurality of containers with the delivered proppant at the loading station, such that the inner volume is substantially filled with proppant, the proppant substantially being evenly distributed in the inner volume of each of the one or more containers upon loading completion;transporting each of the plurality of containers to the well site;positioning each of the plurality of containers on a top surface of a support structure positioned at the well site, the support structure having spaced apart rails extending continuously from a first end to a second end and being positioned to receive the plurality of the containers thereon at discrete cradles so that the plurality of containers are arranged in a side-by-side arrangement and separately moveable on and off of the support structure; anddischarging the loaded proppant from one or more of the plurality of containers positioned on the support structure by selectively moving the gate so that the proppant flows from within the inner volume through the outlet. 2. The process of claim 1, wherein the step of transporting the plurality of containers to the well site comprises: providing a single container of the plurality of containers on a trailer of a truck at the loading station after the single container is loaded with proppant; and trucking the single container by the truck from the loading station to the well site. 3. The process of claim 2, further comprising: storing the plurality of containers at the loading station prior to the step of transporting the containers by stacking a first container of the plurality of containers on top of a second container of the plurality of containers; andstoring the discharged containers at the well site in a stacked arrangement. 4. The process of claim 1, further comprising: moving one of the plurality of containers having proppant stored therein with a forklift from the loading station onto a trailer or a bed of a truck;removing the one of the plurality of containers from the trailer or bed of the truck with a forklift; andtransporting the one of the plurality of containers by the forklift to the support structure to position the one of the plurality of containers directly on the top surface of the support structure and upstream of a conveyor that transports proppant from the one of the plurality of containers to a location at the well site. 5. The process of claim 1, the step of discharging comprising: discharging the loaded proppant from one or more of the plurality of containers into a hopper, the hopper positionally extending below the support structure. 6. The process of claim 5, the step of discharging further comprising: discharging the loaded proppant from the hopper into a tubular member. 7. The process of claim 6, the step of discharging further comprising: applying compressed air to the tubular member so as to draw the proppant along a length of the tubular member for delivery to the well site. 8. The process of claim 6, the step of discharging further comprising: applying a screw conveyor to the tubular member so as to draw the proppant along a length of the tubular member for delivery to the well site. 9. The process of claim 1, further comprising positioning the plurality of containers on the support structure to align the gate of each of the plurality of containers with one or more actuators, each actuator of the one or more actuators corresponding to one of the plurality of containers, the actuators selectively moving the gate between the open position and the closed position. 10. The process of claim 9, wherein each of the one or more actuators is positioned to be selectively actuated so as to selectively move the gate between the open position and the closed position. 11. The process of claim 1, wherein the step of loading the plurality of containers comprises loading proppant into each of the plurality of containers such that the weight of the proppant loaded into each of the plurality of containers is approximately less than forty-eight thousand pounds and such that each of the plurality of containers is arranged to be shipped on a truck along a highway, and wherein each of the plurality of containers has a length of about ten feet or less, a width of about eight feet or less, and a height of about eight and one-half feet or less so as to accommodate less than approximately forty-eight thousand pounds of the proppant and allow the interior volume to be substantially filled so as to leave little void space. 12. The process of claim 1, wherein the ramps are positioned adjacent the bottom of the container and closely arranged to extend to the outlet, wherein the plurality of containers comprises a multiplicity of containers being positioned in a side-by-side relationship on and spaced-apart along the support structure, and wherein the support structure includes a plurality of rails positioned to create a substantially rectangular-frame that extends in a substantially horizontal plane and onto which the multiplicity of containers is positioned, and a plurality of legs each extending downwardly from the rectangular-frame so as to support the rectangular-frame above an underlying surface when the multiplicity of containers is positioned thereon. 13. The process of claim 1, wherein two or more of the lateral sidewalls include a plurality of vertically extending lateral wall dividers. 14. A process for providing fracking proppant to a well site, the process comprising: providing a plurality of proppant containers, each of the plurality of proppant containers comprising: lateral sidewalls, one or more of the lateral sidewalls having one or more lateral wall dividers,a top,a bottom distal from the top,an outlet in the bottom,ramps extending upwardly at an angle from the bottom toward the lateral sidewalls and each ramp of the ramps terminating at a portion lower than a vertical extent of the lateral sidewalls, the ramps positioned to funnel the proppant toward the outlet;an inner volume at least partially defined by the top, bottom and lateral sidewalls, anda gate adjacent the outlet, the gate being moveable between an open position and a closed position to enable the proppant to flow out of the inner volume;loading each of the plurality of containers with the delivered proppant at the loading station, such that the inner volume is substantially filled with proppant, the proppant substantially being evenly distributed in the inner volume of each of the one or more containers upon loading completion;positioning each of the plurality of containers on a top surface of a support structure positioned at the well site, the support structure having spaced apart rails extending continuously from a first end to a second end and being positioned to receive the plurality of the containers thereon so that the plurality of containers are arranged in a side-by-side arrangement and separately moveable on and off of the support structure; anddischarging the loaded proppant from one or more of the plurality of containers positioned on the support structure by selectively moving the gate so that the proppant flows from within the inner volume through the outlet.
