  • Patent number: 4769922
    Abstract: The invention relates to a method and means for removing liquid from moist metal particles, substantially without causing oxidation, preferably from metal particles produced by means of liquid atomization of a casting jet, wherein the moist metal particles are collected in a space (1) and a non-oxidizing gas flow is blown through them, most of the moisture being caused to accompany the gas flow out of the space (1) and wherein the space, in which the metal particles are filled, is thereafter substantially evacuated so that any remaining liquid is vaporized and thus removed from the space (1).

  • Patent number: 4124377
    Abstract: A method and apparatus for producing metal powder in which a reducing liquid is introduced into the bottom of a substantially closed granulation chamber, and a reducing gaseous atmosphere is produced above the reducing liquid. A stream of molten metal is introduced into the top of the granulation chamber and is acted upon by one or more jets of a pressurized atomizing agent which atomizes the molten metal stream. Metal particles are cooled at least partly in the reducing gaseous atmosphere and are collected in the reducing liquid in the bottom of the chamber, from which they can be withdrawn.
