Hielscher - Ultrasound Technology

Cavitation: Cavitation is created in a fluid by highly intensive ultrasonic waves. Cavitation bubbles increase and subsequently implode within a very short time. The implosion results in high pressures and temperatures and in liquid jet streams with up to 400km/h. The jets hit against the surface of particles or materials and remove the impurities or desagglomerate powders.

Generator: Generates electrical osciallations of ultrasonic frequency (e.g. above 20kHz).

Sonotrode: Mechanical component, that transmitts the ultrasonic vibrations from the transducer to the material to be sonified. It has to be mounted really tightly to avoid frictions and losses.

Transducer: Electro-mechanical component, that converts electrical oscillations into mechanical vibrations. The electrical oscillations are generated by the generator. The mechanical vibrations are transmitted to the sonotrode .
