Title:
POWDER DISPERSION APPARATUS AND FINE POWDER GENERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2013/111431
Kind Code:
A3
Abstract:
The conventional methods are effective for powder with low-aggregability, however, It is difficult to Inhibit powder aggregation of the powder with high-aggregabillty. An objective of the present invention is to provide a powder dispersion apparatus (100) for inducting powder and dispersing the powder by gas jet, comprising a powder-processing container (1), where an internal diameter of a lower portion of the container (1) is gradually reduced downwardly; a gas jet orifice (11) for the gas jet toward a bottom surface of the powder-processing container (1); and an outlet (21) for extracting the powder, having been dispersed and blown upward by the gas jet, from the powder-processing container (1).
