Assembly and method for producing metal powder

An assembly for producing powder, wherein said assembly comprises:

• a melting chamber comprising a transfer device, a melting device and a tundish,
• wherein the melting device comprises a crucible for melting metal material and holding said melted metal material,
• wherein the transfer device is configured to position metal material into the crucible at elevated temperature,
• wherein the crucible is configured for providing a flow path for allowing a flow of said melted metal material from the crucible into the tundish,
• wherein the tundish is connected to an atomizing nozzle,
• wherein the melting chamber further comprises a filtering device with a filtering element which is arranged between the crucible and the tundish,
• wherein the filtering element is arranged in said flow path,
• an atomizing vessel comprising an inlet end,
• wherein the atomizing nozzle is configured to direct molten metal material from the tundish towards and into the inlet end of the atomizing vessel,
• wherein the atomizing vessel comprises an outlet opening which is configured to extract solidified, atomized particles of the formerly molten metal material from the atomizing vessel, and
• a powder processing device connected to the outlet opening of the atomizing vessel,
• wherein said powder processing device comprising multiple separation units,
• wherein each separation unit of said multiple separation units is configured for extracting a different fraction out of the solidified atomized particles from the atomizing vessel,
• wherein the different fractions comprise different weight fractions and/or different size fractions, and for providing multiple different fractions as separate products of the assembly for producing powder.
