The present disclosure is directed to an agitating system having a sub-hopper configured to receive particulate material, an agitator disposed within the sub-hopper and configured to promote movement of the particulate material through the sub-hopper, and a deflector configured to block a portion of the particulate material from exerting a force onto the agitator as the particulate material flows through the sub-hopper. The deflector is positioned such that the agitator extends beyond a first distal edge and a second distal edge of the deflector along a lateral axis.

The present invention provides a method and system for providing on-site electrical power to a fracturing operation, and an electrically powered fracturing system. Natural gas can be used to drive a turbine generator in the production of electrical power. A scalable, electrically powered fracturing fleet is provided to pump fluids for the fracturing operation, obviating the need for a constant supply of diesel fuel to the site and reducing the site footprint and infrastructure required for the fracturing operation, when compared with conventional systems.

Provided is a slurry manufacturing method in which a decrease in slurry quality, an increase in running cost, and a decrease in maintainability are suppressed. A slurry manufacturing device includes: a mixing device (suction pump mechanism portion) that mixes a liquid and a powder to manufacture a slurry; a powder supply device that supplies the powder to the mixing device; and a powder dry box, in which an opening portion of the powder supply device is accommodated in the powder dry box.

A mixing paddle configured for use with a gravimetric blender. The mixing paddle has a first rotor; a second rotor spaced axial from the first rotor; and at least one mixing blade disposed between the first rotor and the second rotor. The at least one mixing blade of the mixing paddle includes an inner edge having a first sloped portion and a second sloped portion directed inward toward a middle portion of the at least one mixing blade. The mixing blade is configured to be narrower in the middle portion between the outer edge and the inner edge than at a first end and second end.

Systems and methods for managing bulk material efficiently at a well site are provided. The disclosure is directed to a container support frame that is integrated into a blender unit. The support frame is used to receive one or more portable containers of bulk material, and the blender unit may include a gravity feed outlet for outputting bulk material from the containers directly into a mixer of the blender unit. The blender unit with integrated support frame may eliminate the need for any subsequent mechanical conveyance of the bulk material (e.g., via a separate mechanical conveying system or on-blender sand screws) from the containers to the mixer. As such, the integrated blender unit may be lighter weight, take up less space, and have a lower cost and complexity than existing blenders.

A blender has a mixing chamber for reception of materials to be blended. A mixing screw is mounted at a bottom of the mixing chamber for mixing materials within the mixing chamber and delivering mixed materials to an outlet feeding a processing line. The blender has a plurality of material handling compartments. One or more cleaning air jets are provided in each material handling compartment. The cleaning air jets are operable to direct material towards an outlet of the compartment. Each cleaning air jet is connected to a pressurised air supply through a valve which controls delivery of pressurised air to the cleaning air jet.

An improved system and method for fluidizing dry powder-based additives into downhole well operations utilizes a dried, low-volume air stream and an ejector nozzle in order to disperse the powders into a liquid stream. In an embodiment, the system can be placed on a powder blending trailer in order to convey additives directly from bulk transport bins into a liquid stream, through the use of an atmospheric pressure hydration tank fitted with a cyclone separator to ensure an even dispersal into the liquid stream.
