Provided is a classifier capable of classifying smaller microparticles and obtaining a narrower particle size distribution. The classifier includes a classification rotor constituted of a cylindrical body having a plurality of classification blades in an outer circumference portion thereof and having also an opening portion that opens in one lateral face thereof along an axis of the cylindrical body, a device body that accommodates the classification rotor and holds the classification rotator rotatably about the axis and that introduces classification-target powder from the outside and feeds the powder to the outer circumference portion of the classification rotor, and a discharging portion for drawing the powder classified by the classification rotor and removing the power to the outside of the device body, wherein a rotational shaft portion extending from an open face of the constriction portion to the other lateral face of the classification rotor has a diameter that increases progressively toward the other lateral face.

The effects of oxygen, applied DC voltage and surface orientation on the wettability of ceramics by liquid metals are clarified and new methods for metal-ceramic joining are proposed based on information from wetting experiments, using three examples. The strengths of Ni-Al2O3 joints obtained at very low oxygen potentials are higher than in high oxygen potential environments. Applying a DC voltage to the interface between metals and partially stabilized zirconia is shown to improve the strength of metal-zirconia joints. Cu and SiC can be strongly joined without using active elements such as Ti and Zr by controlling the joining conditions. © 2010 Acta Materialia Inc.

Powder technology is widely utilized for food applications. In particular, fine milling has become an important unit operation in recent years. The air classification mill, pin mill and fluidized-bed opposed jet mill were tested in the preparation of ground soybeans. The air classification mill could not continuously operate due to overload, resulting from the blockage of ground material. Thermal analysis of soybeans revealed the difficulty in preventing this phenomenon. The pin mill was able to grind soybeans down to 10-30μm at a throughput of 12kg/h. A finely ground product with a particle size of 10μm was obtained only by repeated milling, meaning that the product ground by pin milling was processed again using the same machine. A fluidized-bed opposed jet mill could grind the soybeans by processing the pin mill product down to 5μm at 20kg/h. The combination of mill and air classifier was able to increase the protein ratio in the starch-rich seeds. The mill not only produced fine particles but also separated the protein from starch granules in the system. The air classifier acts to separate the released protein from the starch granules by exploiting their size differences.

Disposed is a jet mill that has a cylindrical pulverization chamber (10) and a classification chamber (6) that connects to the pulverization chamber (10). A fine-powder discharge port (4a) and a classification rotor (7) are provided in the classification chamber (6). A feedstock supply port (5) and at least one gas emission nozzle (11) are provided in the pulverization chamber (10). The shape of the classification chamber (6) is a cone that starts on the inner wall of the pulverization chamber (10), and is angled towards the classification rotor (7). This configuration gives the jet mill high efficiency of pulverization and reduces the amount of powders left in the chamber when the jet mill has finished running.
