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.

Proppant discharge system and a container for use in such a proppant discharge system

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.

Proppant discharge system having a container and the process for providing proppant to a well site

A spreader assembly for spreading a material and for mounting to a bed of a truck is disclosed. The assembly includes a hopper and a frame having an upper rail for supporting the hopper in the bed of the truck. The frame includes a pair of front and rear posts extending downwardly from the upper rail and an upper rail extending in a cantilevered fashion from the rear posts to support the outlet spout outside the bed of the truck. A quick-release connector releasably engages the frame for preventing longitudinal movement within the bed of the truck. A spinner is rotatably attached and is moveable between an operating position and a storage position. The hopper includes a lower portion having a bottom with a first slanted portion having a first slope and a second slanted portion having a second slope with the first slope being different than the second slope.

Truck bed mounted spreader

Material discharge apparatus comprising, in one embodiment, a material receiving hopper (42) which can be attached to the outlet of a silo (40) and carrying a conical closure member (47) which is mounted on an actuating cylinder (45) to be raised and lowered with respect to the wall of the receiving hopper (42) thus to determine and control the flow of material from the silo (40) into and through the receiving hopper (42), there being a vibrating motor (21) adapted to impose a vertical oscillatory motion on said closure member (47) thus to promote the free flow of material through the annular opening created when the closure member is in its raised position, the height of the member in this position being determined, for example, by a control device (51) whereby the rate of flow of material can be varied.

Material discharge apparatus

An apparatus for discharging flowable material, particularly a powder or other particulate material, is provided with a hopper, bin, silo or the like having a discharge outlet with a closure, also known as an α-flange, and spaced therefrom a device, such as a cone, for obturating flow of material from the outlet, and a mechanism which is connectible with the obturating device and is operative to open the closure and obturating device in sequence. The mechanism also closes the obturating device and closure in reverse sequence.

Apparatus for discharging flowable material having a closure and an obturating device

Apparatus for controlling discharge from a silo, comprising a device mounted internally of a discharge opening for flowable material and forming with that opening a flow path for material through the opening. A bellows actuator associated with the device moves the device relative to the discharge opening to close the opening or to open it to a desired extent. A vibrator carried by the device vibrates the device to assist flow of material through the discharge opening when it is open.

Apparatus for controlling discharge from a silo

of EP0049992The invention relates to apparatus 1 for controlling discharge from a store thereof such as a silo 4, the apparatus 1 including a conical device 2 which supports on its undersurface a vibrator 7 and which is itself supported via isolators 11 on cross-beam 10. The maximum diameter of the free edge of the device 2 is less than the internal diameter of an opening 3 from the silo 4 and defines with that opening an annular flow path 9 through which material (not shown) above the device 2 flows when the vibrator 7 is vibrated, as vibrating the device 2 to initiate flow of material through the path 9.
