The EIGA spherical metal powder vacuum gas atomization equipment, with its unique advantages and wide range of applications, has become a key technological apparatus in metal powder production.

Working principle of EIGA powder making:
The working principle of vacuum gas atomization is to melt metals and metal alloys under vacuum gas protection conditions. The metal liquid falls down through the insulated crucible and the guide nozzle, and the high-pressure airflow through the nozzle atomizes the metal liquid into a large number of fine droplets. The fine droplets solidify into spherical and sub-spherical particles in flight, and then are screened and separated to prepare metal powders of various particle sizes.

Working principle and application of EIGA powder making equipment:
The rotary electrode induction melting vacuum gas atomization powder making equipment is a device used to prepare titanium alloy powder, high-temperature alloy powder and active alloy powder. Under appropriate vacuum conditions and protective gas conditions, the prefabricated alloy rods are regionally refined, and the metal liquid flows vertically through the nozzle continuously and downward. The metal liquid is atomized and broken into a large number of fine droplets by the high-pressure airflow through the tightly coupled nozzle, and the fine droplets solidify into particles in flight. The powder gas mixture is sent to the cyclone separator through the conveying pipe, where the coarse powder, fine powder and atomizing gas are separated, and the metal powder is collected in a sealed container.

This powder making equipment is mainly used in the production of high-grade and high-tech metal powders. The main indicators are: good sphericity, high purity, low oxygen content, rapid solidification, uniform microstructure, etc.
