Abstract (en)
[origin: EP0331993A1] Arranged in a closed atomising tank of such an apparatus, the said tank comprising a melting chamber and an atomising chamber, are a melting crucible, a pouring funnel and an atomiser nozzle, by means of which the molten metal is atomised by pressurised fluid as atomising medium taken from a storage container via a force pump and collected in the atomising chamber connected to the melting chamber. According to the invention, the atomiser nozzle (5) has at least two discrete fluid outlet openings, which are arranged symmetrically around the falling stream of melt, and arranged between the atomising tank (1, 6) and the fluid storage tank (16) is a compensation line (17) via which the gas volume displaced by the fluid is recirculated from the atomising tank (1, 6) into the storage container (16) from which the fluid is taken. <IMAGE>
