Abstract

In a device for atomising at least one jet of a liquid or solid material, preferably molten metal, the atomising process takes place in a stationary ultrasonic field which is produced between at least one pair of ultrasonic vibrators. In order to increase performance, a plurality of atomising fluid jets, and in a complementary fashion thereto additional fluid jets (e.g. gas) are introduced from nozzles in each node point area of the stationary ultrasonic wave. In this way, the atomisation fluid mass throughput is very greatly increased and thus the atomisation power raised. In addition, special sonotrode shapes are proposed in order to increase the performance further. <IMAGE>
