Abstract
A device for the manufacture of spherical metallic powder comprising a vertical cylinder-conical vessel having in an upper part, means for introduction of a stream of liquid metal and for atomizing said stream using jets of gas and, in a lower part, gas inlet means for producing upwardly inclined tangential jets of gas for generating vortices along an ascending spiral centered on the axis of the vessel. The device also comprises a gas outlet connected to a cyclone dust remover whereby metal powder carried by the gas is separated from the gas, the gas outlet of the cyclone dust remover being connected to the gas inlet means and the dust outlet of the cyclone dust remover being connected to a duct opening into the vessel in the immediate vicinity of the jets produced by the gas inlet means.
