FIELD: powder metallurgy, construction material, mechanical engineering. SUBSTANCE: production line has reservoir-water accumulator, melting furnace, metal accumulator, disperser, spraying chamber, water cleaning filter, drying unit. Production line is further provided with refrigerating machine, hydraulic classifier, mixer, mechanical dehydrator and gas discharge device. Refrigerating machine is communicated with reservoir-water accumulator, which has two interconnected sections: cold water section and warm water section. The latter is connected with disperser. Spraying chamber is connected with hydraulic classifier which is connected in series with gas discharge device and mechanical dehydrator, which is communicated with vacuum drying unit, gas discharge device and mechanical dehydrator connected with vacuum drying unit, gas discharge device and water cleaning filter. The latter is connected with warm water section of water accumulator. EFFECT: increased efficiency, improved quality of powder, reduced explosion hazard and improved air medium contamination control. |
