A proppant discharge system has a container with an outlet formed at a bottom thereof and a gate slidably affixed at the outlet so as to be movable between a first position covering the outlet to a second position opening the outlet, and a support structure having an actuator thereon. The container is removably positioned on the top surface of the support structure. The actuator is engageable with gate so as to move the gate from the first position to the second position. A conveyor underlies the container so as to receive proppant as discharged from the container through the outlet. The container is a ten foot ISO container.

Granular material flows out through the discharge opening of a silo and through a sealed housing to a target location. A vent opening in a top portion of the silo has a vent cover operative to selectively open and close the vent opening. When the vent cover is closed, air movement into an upper portion of the silo is prevented. A gate is operative to control a flow of granular material through the discharge opening. A vacuum conduit has a lower input end thereof connected to an interior of the housing, and an upper output end thereof located in an upper portion of an interior of the silo. Material flowing out of the silo creates a vacuum drawing dust from the housing up the vacuum conduit into the silo.

The present invention is a modular system for delivering material directly to a blender hopper. The system includes primary base and optional secondary base modules supporting surge hoppers which receive material from material containers. The surge hopper may then dispense the material directly and rapidly to the blender hopper by gravity feed. During continuous operation, exhausted material containers may be removed from the surge hoppers and replaced with full material containers as material empties from the surge hoppers. This allows steady, high-volume flow of material to the blender hopper.

A proppant discharge system has a container with an outlet formed at a bottom thereof and a gate slidably affixed at the outlet so as to be movable between a first position covering the outlet to a second position opening the outlet, and a support structure having an actuator thereon. The container is removably positioned on the top surface of the support structure. The actuator is engageable with gate so as to move the gate from the first position to the second position. A conveyor underlies the container so as to receive proppant as discharged from the container through the outlet. The container is a ten foot ISO container.
