A dynamic mixer for mixing a multi-component material includes a mixing rotor capable of being rotated about an axis of rotation, the mixing rotor having a coupling socket configured at an end thereof. The coupling socket has a reception space configured to receive at least a part of a polygonal shaped coupling plug of a drive shaft to transfer torque from the drive shaft to the mixing rotor. The reception space has an inner length in the direction of the axis of rotation and has an inner surface extending over the inner length and surrounding the axis of rotation.

A dynamic mixer attachment is disclosed, which is adapted for use with conventional multi-component cartridges. The mixer has dispensing and drive axes that are offset relative to each other to enable use of the mixer with conventional multi-component cartridges. Also disclosed is a dispenser adapted for use with the mixer attachment and conventional multi-component cartridges.

A reactor is described. The reactor comprises a housing having a reaction space to accommodate a reactant; an outlet pipe connected to a lower part of the reaction space; a rotating shaft disposed in the housing; and a plurality of stirring blades mounted on the rotating shaft. The housing has a lower converging region, and a cross-sectional area of the lower converging region decreases toward the outlet pipe. At least one of the plurality of stirring blades is located in the lower converging region. The outlet pipe includes a first region connected to the lower converging region and a second region extending from the first region in a discharge direction, a cross-sectional area of the first region decreases in a direction from the lower converging region toward the discharge direction, and the second region has a constant cross-sectional area.

This invention is directed toward a mixing vessel and mixer where the design of the mixer and mixing vessel allow the mixer to reach all the cracks and crevices of the mixing vessel. The mixer also has two opposing openings with mixing vanes that facilitate turbulence and blending through a strong centrifugal flow. The mixer has unbroken or minimally broken surfaces for grinding/shearing lumps into a smooth, lump-free paste.

There is provided a stirring device including a stirring tank including an inner peripheral wall which is circular in cross section, at least one circulating impeller and at least one dispersion blade which are located inside the stirring tank and rotatable around a vertical axis independently of each other, and a guide ring disposed radially outward near the dispersion blade. The circulating impeller is disposed along the inner peripheral wall of the stirring tank, and rotates around the vertical axis to form at least a downward flow in a stirring object existing inside the stirring tank. The dispersion blade rotates to apply a shear force to the stirring object, and is disposed at a radially inner position of the stirring tank from the circulating impeller, and at a position in contact with a flow of the stirring object, which is formed by the circulating impeller.

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.

A method of mixing using a tubular reactor wherein process material continuously passes through the tubular reactor which is operating at predetermined reaction conditions. The tubular reactor is rotated through reciprocating arcs about the longitudinal axis of the tube as the process material passes therethrough. Static and/or dynamic mixers or agitators may be provided within the tubular reactor.

A positive active material manufacturing method according to an exemplary embodiment of the present invention includes: a step of preparing a lithium-containing compound; a step of manufacturing a coating liquid including at least one coating element; a step of mixing the lithium-containing compound and the coating liquid to form a coating mixture of a clay or slurry state; and a step of agitating the coating mixture. Further, a manufacturing apparatus of a positive active material according to an exemplary embodiment includes a rotation container, a cover, a nozzle, and an agitation wing.

In a reactor apparatus including a reactor having a straight body, an agitation shaft, and an agitating blade, dimensions of the straight body, dimensions of the agitating blade, and a set value of a number of rotations of the agitation shaft satisfy a relationship represented by N(b/d)(L/D)/n?6.0. N represents a number of agitating blades, b represents a maximum value [m] of blade widths of the agitating blades, d represents a maximum value [m] of blade diameters of the agitating blades, L represents a length [m] of the straight body in an extending direction, D represents a maximum value [m] of diameters of inscribed circles substantially inscribed in the straight body, and n represents the set value of the number of rotations [rps] of the agitation shaft.

An apparatus can include a hollow tube, central shaft, agitation components, and bidirectional fluted auger. The hollow tube can have an inlet, outlet, and longitudinal central axis, and can facilitate the conveyance of foodstuff materials from the inlet to the outlet. The central shaft can extend along the longitudinal axis and can be rotationally driven both clockwise and counterclockwise. The agitation components can be coupled to the central shaft and can agitate and mix foodstuff materials being conveyed along the hollow tube. The bidirectional fluted auger can be coupled to the central shaft proximate the outlet, can rotate with the central shaft when the central shaft is rotationally driven, and can have a flow rate limiting inner cylinder, clockwise-progressing flute features, and counterclockwise-progressing flute features. The clockwise and counterclockwise progressing flute features can convey foodstuff materials toward the outlet when the bidirectional fluted auger is rotated clockwise or counterclockwise.
