FIELD: process engineering. ^ SUBSTANCE: invention relates to device (10) intended for processing powder materials that incorporates work chamber (16) to process material therein. Device bottom (18) is formed by several overlapping circular guide plates (22-24) arranged one above the other. Circular slots (25, 26) formed there between allow work air to flow there through. At the center of said bottom (18) there is circular-slot-like nozzle (30) with its sprayer can spray fluid in the form of flat jet (44), approximately, parallel to bottom plane. ^ EFFECT: optimum transfer of powder material particles and material processing. ^ 9 cl, 2 dwg |
