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).
