A dispersing device is provided by which a dispersion with a high yield and a proper dispersing process can be carried out. The dispersing device causes a mixture of a slurry or a liquid to flow by centrifugal force toward an outer circumference between a rotor and a stator. It comprises a container, a cover assembly that closes an upper opening of the container, a stator that is fixed under the cover assembly, a rotor that is disposed to face a lower surface of the stator, and an assembly for supplying the mixture that stores an unprocessed mixture to be supplied to a gap between the rotor and the stator. The assembly for supplying the mixture has a body, a first member for injecting the mixture, and a second member for injecting the mixture.

The invention relates to a capsule for producing a composition, particularly for dental care, comprising an enclosure provided with at least two compartments, the number of compartments corresponding to the number of components to be mixed, and at least one wall for isolating the components, said wall being provided to isolate the components from each other in storage mode, and to allow fluidic communication between the compartments in mixing mode, said capsule also comprising a shank for removable attachment to a hand-held part.

A method of producing a paste for production of a negative electrode of a lithium ion secondary battery, which includes a negative electrode active material, a thickening agent, and an aqueous binder. The method includes preparing a mixture containing the negative electrode active material and the thickening agent by dry mixing the negative electrode active material and the thickening agent in a powder state under reduced pressure; preparing a paste precursor by adding one or two or more kinds of liquid components selected from an aqueous medium and an emulsion aqueous solution containing the aqueous binder to the mixture and wet mixing the mixture; and preparing the paste for production of a negative electrode by further adding one or two or more kinds of liquid components selected from the aqueous medium and the emulsion aqueous solution containing the aqueous binder to the paste precursor and wet mixing the mixture.

A continuous ready mix joint or texture compound manufacturing system and a method for continuously manufacturing a ready mix joint or texture compound includes a continuous mixer having an inlet and an outlet, a pump disposed at the outlet of the continuous mixer, and a disperger having an inlet and an outlet. The continuous mixer is adapted to receive at least one dry ingredient and at least one wet ingredient at the inlet and continuously mix the at least one dry ingredient and the at least one wet ingredient to form a mixed composition. The pump is adapted to pump the mixed composition from the outlet of the continuous mixer to the inlet of the disperger. The disperger is adapted to receive the mixed composition and apply a shear force to the mixed composition to form a homogenized, disperged composition.

A device for dispersing a water-soluble polymer in powder form having a standard particle size of less than 1 mm, includes: a wetting chamber, a chamber for grinding and discharging the dispersed polymer with a horizontal axis of revolution, and a mechanism for connecting the wetting chamber to the grinding chamber in the form of an L-shaped tube. The upper and lower parts of the wetting chamber and the L-shaped tube have an internal surface with an identical surface tension (TS1). The cover of the wetting chamber has an internal surface with a surface tension (TS2) higher than the surface tension (TS1) of the internal surface of the upper and lower parts of the wetting chamber and the L-shaped tube.

An apparatus and method for mixing a liquid having particulate includes a vessel for containing me liquid an axial impeller rotating about a substantially vertical axis. The impeller is adapted for submerging below the liquid surface by a distance approximately one-quarter to one-half of the height of the liquid. The impeller is oriented upwardly to produce (a) an inner, upward flow region located along the vertical axis of the vessel, (b) a transition flow region above the impeller in which liquid moves radially outwardly toward the vessel sidewall, and (c) an outer, downward flow region located along the sidewall. The impeller spins at a variable speed, such that the flow is capable of entraining solid particles having a settling velocity of up to approximately 1 foot per minute in the liquid, and the speed of the impeller is chosen to enable particles having a desired settling velocity to settle to the vessel bottom.

Provided is method of making an aqueous composition comprising (a) providing a mixer comprising a sealable volume and one or more rotors inside said sealable volume; (b) placing into said sealable volume ingredients comprising ethylcellulose polymer and fatty acid; (c) placing into said sealable volume ingredients comprising water and a water-soluble base; (d) sealing said sealable volume after said steps (b) and (c); (e) then rotating one or more of said rotors while said ingredients are at a temperature above the softening point of said ethylcellulose polymer, to produce said aqueous composition; wherein said step (e) is conducted so that 90% or less of the volume of said ingredients is uncontacted by one or more of said rotors.
