A mixing apparatus for mixing powder and liquid, includes: an apparatus main body having an internal space; a cylindrical member arranged in the internal space with one end facing upward and the other end facing downward, the one end and the other end being opened; a powder dispersing portion arranged above the apparatus main body, the powder dispersing portion dispersing the powder into a space of the cylindrical member; a liquid spraying portion arranged in a vicinity of the powder dispersing portion, the liquid spraying portion spraying the liquid into a space of the cylindrical member; a collection portion arranged below the apparatus main body, the collection portion collecting a mixed powder consisting of the powder dispersed by the powder dispersing portion and the liquid sprayed by the liquid spraying portion; a filter arranged around the cylindrical member in the internal space; and a discharge port discharging air in the internal space through the filter.

Mixing apparatus for mixing powder having liquid repellent property and liquid

A method for concentrating a particular component in powder by performing a mechanical dry processing on powder formed by granulating a solution containing two or more components, producing chips in a fine-powder form by chipping away at particle surfaces of the powder where a larger amount of the particular component is contained than particle interior portions of the powder, classifying the powder into fine powder containing the chips and coarse powder containing particles whose surfaces have been chipped away, and collecting the fine powder containing the particular component.

Method for concentrating particular component in powder

The powder classifying apparatus classifies raw material powder having a particle size distribution into fine powder and coarse powder and includes a disk-like centrifuge chamber formed as a space between two facing members, a plurality of air nozzles for supplying gas into the centrifuge chamber to generate a whirling stream, a raw material ejecting nozzle for supplying the raw material powder to the whirling stream generated in the centrifuge chamber, a fine powder collecting tube disposed in a central portion of one of the two facing members and communicating with the centrifuge chamber to discharge the gas including the fine powder separated in the centrifuge chamber to the outside, a cylindrical first wall disposed at an opening portion formed of the fine powder collecting tube, and a cylindrical second wall disposed on the other one of the two facing members and facing the first wall with a given interval.
