Abstract

The invention relates to an apparatus for pulverizing at least a jet of a quid or solid material in a standing ultrasonic field which is generated between at least a pair of ultrasonic devices. To increase the pulverizing capacity a plurality of pulverizing fluid jets and in addition supplementary fluid jets, for example a gas is introduced through separate nozzles at each nodal pressure area of the standing ultrasonic wave. In addition the pulverizing capacity is further increased by providing special horn shapes of the ultrasonic devices.
