A material application system includes a hopper assembly and a conveyor assembly. The hopper assembly includes an upper portion and a downcomer portion. Bulk material is loaded into the upper portion and passes through the downcomer portion. The downcomer portion may include a sail plate for agitating the bulk material to inhibit the formation of clogs in the bulk material.

A proppant discharge system has a container with an outlet positioned in a bottom thereof and a gate affixed adjacent 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 can be a ten foot ISO container.

A scale controller system and method of using the system is disclosed. The scale controller is adapted for use with a grain cart or similar implement that includes a discharge opening and conveyor. The system includes a scale and a plurality of sensors that work together to automate numerous functions that are typically performed manually. For example, the present invention discloses a system that automatically records the amount of material loaded or unloaded by continuously monitoring the load on a scale and the RPMs of a power take-off shaft that drives a conveyor.

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.

A discharge valve for discharging a food product may be arranged at a low point of a vessel. The discharge valve includes a valve body, a valve seat, a valve plug and an arm. The valve plug is attached to a first end of the arm and a second end of the arm is attached to a pivot point that is arranged inside the valve body. The arm is configured to pivot the valve plug between a valve closed position where the valve plug abuts the valve seat, and a valve open position where the valve plug is pivoted away from the valve seat, to a location where the valve plug is positioned at least partly within the valve body.

A proppant container facilitates the transportation of wet sand for use in a hydraulic fracturing operation. The container is mounted in a cradle that tips downward in arcuate motion for discharge or proppant through a top opening The tipping mechanism may be driven by a system of gears or a hydraulic ram.

Systems and methods for using one or more pre-filled, portable containers, instead of pneumatic transfer, to move bulk material from a transportation unit to a blender receptacle of a blender are provided. A transportation unit may deliver one or more containers of bulk material to the well site, where the containers may be disposed in an elevated position around the blender receptacle. A gravity feed outlet may extend from one or more containers to route bulk material from the one or more containers directly into the blender receptacle. Since the transportation unit is able to unload the portable containers of bulk material without pneumatic transfer, the stackable containers may enable a cleaner and more efficient bulk material transfer at the site.
