A feeder system includes a donut-ring-shaped first wheel having a first groove recessed below its top surface, with a first hopper positioned above to receive material. A first conduit connects the hopper bottom to the groove, defining a feeding path. A mixer unit receives materials, connected to the first groove via a first suction head. A first motor rotates the first wheel, transferring material from hopper to groove to mixer unit. A donut-ring-shaped second wheel includes a second groove, second hopper, and second conduit. A second suction head connects this groove to the mixer unit, while a second motor enables wheel rotation for material transfer. The mixer unit combines both materials. The feeder system implements coaxial wheel arrangement with independent material flow control, enabling independent powder delivery for additive manufacturing applications.

An impeller assembly for a solid-liquid mixing device, and a solid-liquid mixing device using the impeller assembly. The impeller assembly comprises an impeller. The impeller comprises a truncated conical body. Multiple mixing blades are formed from top to bottom on an inclined surface of the body. The impeller assembly further comprises at least one blocking plate provided on an outer side of a lower portion of the body. The mixing device further comprises: a housing; at least one solid supply apparatus; at least one liquid supply apparatus; a mixing chamber defined by corresponding portions of the body and the housing; and a dispersion chamber provided between a flow channel outlet at a lower portion of the mixing chamber and a discharging apparatus.

A multi powder mixing system includes first, second and third wheels each having a first groove recessed below its top surface, with first, second and third hoppers positioned above the wheels. First, second and third conduits connect the hopper bottoms to the grooves, defining feeding paths. A mixer unit receives materials, connected to the grooves via first, second and third suction heads. First, second and third motors rotate the respective wheels, transferring powdered materials from the hoppers to the grooves to the mixer unit. The mixing system has a coaxial wheel arrangement with independent material flow control providing controlled powder mixing.

A system for electric-motor driven transportation mechanism for fracturing operations is disclosed. The system can include a transportation mechanism to transport blending components from a first tub to a second tub through chutes that are disposed in a side area between the first tub and the second tub; a variable frequency drive (VFD) that provides real-time control of a frequency or speed of an electric motor associated with the at least one transportation mechanism to control transportation of the blending components; one or more sensors configured to detect a level of proppant in the first tub and transmit a signal to a control unit associated with the least one transportation mechanism, wherein the control unit is configured to receive the signal from the one or more sensors and provide real-time control of the VFD based on the signal.

The disclosed apparatus, systems and methods relate to devices, systems and methods for mixing particulate matter such as salt with moisture. In various implementations, the mixer is transportable. In various implementations the mixer comprises a hopper, at least one auger, and a mixing housing. Various implementations, additionally include at least one liquid tank.

In a general aspect, the present disclosure relates to a blender system for use in a hydraulic fracturing system. The blender system includes a mixing tub and a movable divider associated with the mixing tub. The divider is movable between an open position and a closed position. When the divider is in the open position, liquid can flow between a first portion of the mixing tub and a second, distinct portion of the mixing tub. When the divider is in the closed position, the divider prevents liquid flow between the first and second portions. A divider control system can move the divider between the open and closed positions. A first input pump pumps fluid into the first portion of the mixing tub, and a first output pump pumps fluid from the first portion of the mixing tub. A second input pump pumps fluid into the second portion of the mixing tub, and a second output pump pumps fluid from the second portion of mixing tub.

A jet device for mixing and dispensing glue. The jet device structurally includes glue feeding modules, a glue mixing module, a glue dispensing module, a cooling module, and a control module, where the at least two glue feeding modules are arranged, are in fluid communication with the glue mixing module through individual glue channels, and are capable of quantitatively conveying two-component glue at a constant pressure; a glue blending cavity and a spiral stirrer are arranged in the glue mixing module, two components of the glue converge in the glue blending cavity and are dynamically stirred and mixed by a stirring paddle, and stirring thrust pushes and guides the mixed glue to flow into the glue dispensing module; and the glue dispensing module drives, through a piezoelectric jet valve, a valve rod to move, to accurately jet the mixed glue.

A slurry homogenization process and a use thereof, including the following steps: performing a first pre-mixing operation on a main material, a first conductive agent, and a binder to obtain a first mixture; adding the first mixture into a first solvent, and sequentially performing a second pre-mixing operation and a first dispersing operation to obtain a second mixture; and adding a conductive slurry into the second mixture, sequentially performing a third pre-mixing operation and a second dispersing operation to obtain a third mixture, and performing a defoaming and cooling operation on the third mixture to obtain a homogenized slurry.
