Abstract

A device for gas atomizing a liquid stream (41), such as a stream of molten metal or metal alloy, has an atomizing device (43) including, for example, an annular opening for receiving the stream. The atomizing device is arranged for applying atomizing gas to the stream so as to form a spray (50) of atomized particles. The atomizing device includes at least one atomizing rotor (45) which produces an atomizing gas flow field which is asymmetric with respect to the axis of the stream whereby, by varying the positional relationship of the symmetric gas flow field with respect to the stream, movement is imparted to the spray. The atomizer itself may also be tilted to and fro, the movements in combination enabling more flexibility with improved uniformity and control of deposition.
