Navector ultrasonic system

The production of ultrasonic sieves is simplified very much by using the Navector method, because the cloth waveguide does not need to be tuned and the support elements to the frame are not to be fixed in the nodal points.

Coupling the cloth waveguide to the frame, results in a better ultrasound distribution across the sieving mesh, as the ultrasonic energy is conducted to the frame, as well as from the frame to the screen cloth.

By positioning the converter outside the frame, the following advantages are generated:

• sieving powder deposits do no longer stick to the converter
• simplified and therefore cheaper support mechanics between converter and frame
