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.

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.

The present invention provides a mechanism in which the power of a vortex flow can be maintained strong so as to efficiently mix a liquid and a powder. A system for mixing liquid and powder according to the present embodiment is provided with: a powder-liquid mixing unit 20 which has a casing 21 for accommodating therein a powder and a liquid to be mixed together and discharges a mixture from an outlet opening 27 at the bottom of the casing 21; a powder supply unit 10 which is disposed above the powder-liquid mixing unit 20 and supplies a powder to the casing 21; an injection unit 22 which is provided at an upper portion of the casing 21 and injects a liquid into the casing; and a first pump 30 which is connected to the outlet opening 27 of the casing 21 and suctions the mixture inside the casing.

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.
