Powder treating apparatus

Abstract

There is provided a powder treating apparatus which can uniformly and successively combine and grow powders having different specific gravities or sizes together with a simple structure. The apparatus comprises a rotating containerinto which plural kinds of powders P having different specific gravities or sizes are supplied and which rotates in a predetermined direction, a fixed containerretaining the rotating container, primary treating means Mwhich is so arranged as to face an inner periphery surfaceS of the rotating containerand to extend in an axial direction, generates turbulence flow including eddying flow together with a rotational motion of the rotating container, and stirs and mixes the powders P having different specific gravities or sizes, a communicating holefor ejecting the powders P stirred and mixed by the primary treating means Mto a predetermined treatment space around the rotating container, and secondary treating means Mwhich applies planar compressive shear force to the powders P ejected from the communicating holewith an inner periphery surfaceS of the fixed containerto carry out a composite treatment, and causes the powders P having undergone a composite treatment to flow back in the rotating container.
