A site may require that multiple containers, such as bulk material containers, may be utilized to provide a required composition or mixture of materials at a required discharge rate. An arrangement of four or more containers on a frame disposed on a support platform where two faces of each container proximate or adjacent to a face of two other containers to form a rectangle provides a configuration that allows for safe and efficient removal and replacement of containers A rotary table coupled to a motor disposed on the support platform rotates the frame such that each container transitions to different positions. The containers discharge material through an opening of support platform. Containers may be retrieved from one position and replaced at another position or retrieved and replaced from a single position. Such a configuration allows for multiple transport devices to operate without interfering with the operations of each other.

A hopper-in-frame for transporting granular proppant material, such as oil well sands subjected to fracturing, having a top loading through a hatch in the roof and lateral gravity discharge opening at the level of the hopper floor and not below the hopper through a lower side discharge opening where the load asymmetry is compensated for by the inclusion of an asymmetric roof that includes at least a portion of the roof asymmetrically lowered, such as a sloping roof or sloping to the side of the wall of download. The hopper-in-frame is supported and delimited by a frame that in turn is compatible to be incorporated in intermodal cargo containers.

A silo system includes a storage chamber, an intake pathway associated with the chamber, and a discharge pathway associated with the chamber. The system further includes one or more material sensors associated with the chamber, a plurality of actuators, and a controller that is communicatively coupled to the one or more material sensors and to the one or more actuators. The plurality of actuators enable a deposit of additional material from a transport container into the chamber through the intake pathway at least partially simultaneous with a discharge of material from the chamber through the discharge pathway into an operational silo. The material sensors provide indications of the amount of bulk material in the chamber and the controller is configured to control the one or more actuators in response to sensor data from the one or more material sensors to provide for deposit of material simultaneous with discharge of material.

A feed hopper for a material processing device, in particular for a crusher (10), having two side walls (21) and a rear wall of the hopper (22), wherein the side walls (21) are directly or indirectly coupled to a machine support (12.1) in a swiveling manner and can be converted from a set-up work position to a folded-down transport position and back, wherein a feed area is formed between the side walls (21), and wherein at least one of the side walls (21) is supported relative to the machine support (12.1) in the set-up work position by a supporting device (30). A support lever (31), which in the work position is supported directly or indirectly in relation to the machine support (12.1) by a detachable form-fit connection, wherein the form-fit connection prevents the side wall (21) from folding down, projects into the feed area in the folded-down transport position. In this way, a space-saving design is also achieved in the folded-down transport position.

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 fleet refueling silo tank system gravity feeds fuel through hoses to fleet units without requiring pressurizing pumps. A specialized valve at the fleet unit fuel tank prevents vapor escape and admits fuel at low, gravity-feed pressures. The valve includes a valve body with an upper end and a lower end, the upper end adapted to engage a cap which affixes the valve body to the fuel tank fill mouth. Below the cap, a fuel cut-off plunger and seat selectively interrupt fuel flow through the mouth by responding to a buoyant float extending coaxially beneath the valve body and into the fuel tank. Linkage coupled to the plunger extends through the valve body to the float, and roller bearings within the valve body engage a shaft extending from the float coaxially into the lower end of the valve body.

An apparatus configured for an outlet of a load out silo provided for dispensing proppant from the silo into a storage container. The apparatus comprises a diffuser spout having a housing configured for securing the diffuser spout to the silo outlet and a diffuser element including a first end disposed in the housing, a second end terminating below the housing and a conical sidewall extending between the first and second ends. Flanges extend from the housing for securing the diffuser element thereto.
