An atomizer mixing chamber for a seed treater has a body having first and second inlets for receiving first and second treatment fluids. The atomizer mixing chamber has a first stage cup for receiving and combining the first and second treatment fluids to provide a combined fluid, the first stage cup comprising a first set of holes through which the combined fluid flows. The atomizer also has a second stage cup below the first stage cup for receiving the combined fluid from the first stage cup, wherein the second stage cup further mixes the combined fluid to provide a mixed fluid and wherein the second stage cup comprises a second set of holes through which the mixed fluid flows. The atomizer mixing chamber may include a third stage cup below the second stage cup for receiving the mixed fluid and having a third set of holes through which the mixed fluid exits from the atomizer.

The invention relates to an apparatus and methods for producing liquid colloids such as suspensions of nanoparticles, in which liquid feedstock materials are reacted on a reaction surface of a rotatable plate. The apparatus has a first plate (101) mounted for rotation about a rotation axis (102), the first plate (101) providing a reaction surface (103) having a concave portion; first (106) and second (107) inlet lines arranged to introduce respective first and second liquid feedstock materials to the reaction surface (103); and a collection unit (110) arranged to collect a reaction product formed from reaction of the liquid feedstock materials as a liquid colloid ejected from an outer edge of the plate (101).

A mixing apparatus including a mixing region can have an inlet and an outlet. The mixing region can be operable to couple with a solution housing, thereby defining a mixing chamber. A stem can extend from a surface of the mixing region and the inlet can be disposed at a distal end of the stem. A wing can disposed at a proximal end of the stem and adjacently engaged with the surface of the mixing region and have a leading edge and a trailing edge.

Apparatus for mixing a powdered material with a liquid that includes a housing in which a working space having an inner wall is arranged and a rotatably-driven rotor being arranged in the working space. The rotatably-driven rotor includes a blade ring and bars, which are pointing toward the inner wall and are arranged at different positions in a circumferential direction of the rotor. The apparatus also includes a feed opening for the powdered material being arranged above the blade ring and an annular gap connectable to a liquid supply arrangement being arranged below the blade ring. In a direction parallel to an axial direction of the rotor, the bars one of connect to one another or overlap one another.

A mixer has a circular housing defining a mixing area for mixing and kneading of a gypsum slurry. A rotary disc is positioned in the housing and rotated in a predetermined rotational direction. A rotary driving shaft cointegrally connected with the rotary disc and a plurality of scrapers are positioned in the mixing area. A slurry discharge port is provided on an annular wall of the housing for feeding the gypsum slurry of the mixing area onto a sheet of paper for gypsum board liner. An opening of the slurry discharge port is divided into a plurality of narrow openings, so that fluid resistance on the gypsum slurry flowing out of the mixing area is increased. An annular basal part rotates integrally with the rotary disc and an inner end portion of the scraper is fixed to the annular basal part.

A device for wetting particles, in particular wood particles, with an application agent, at least one conduit transporting a fluid as a fluid stream and an end section which forms an outlet. The fluid can be introduced in the direction of the main flow into a container containing the particles, via the outlet. The particles are in the container in a loosened state and/or can be loosened. The application agent, for spraying by a nozzle device with a speed component directed against the main flow direction, can be introduced into the fluid stream and can be guided to the particles by the fluid stream.

Apparatus and method in which a solid or liquid additive is dispensed within a mixing chamber for mixing with a fluid from the pressurized fluid flow line and is effective mixed in a vortex under vacuum while precluding contamination of the unused additive.

A continuous kneading device is provided with an upper trunk (1) to which a powder supply tube (3) through which quantified powder is supplied is connected and in which the powder is blended with a fluid, and a lower trunk (2) concentrically connected to the bottom of the upper trunk (1). The continuous kneading device continuously kneads the powder and the fluid by a first rotating kneading plate (10) built into the upper trunk (1) and a second rotating kneading plate (11) built into the lower trunk (2), wherein surfaces of the base metals of the first and second rotating kneading plates (10, 11) are covered with a coating material (50) for reducing friction when the powder and the fluid are kneaded together.

A mixing apparatus is provided that evenly mixes a powder raw material and a liquid raw material. The powder raw material is supplied to and spread out on a rotating disk to form a thin layer of dispersed particle swarms close to the periphery of the rotating disk. A rotary atomizer that synchronously rotates on the same axis is provided above the rotating disk. The liquid raw material is supplied to an inside surface of the rotary atomizer. Then, the liquid raw material is conducted to an atomizing head where the liquid raw material is atomized, and droplet swarms are horizontally radiated. The dispersed particle swarms and the droplet swarms are merged and condensed within a tapered wedge-shaped space, with the result that these swarms change into a fine and homogeneous mixture. The mixture is then radiated from the periphery.
