Screening technology
Ultrasonic screener
The ultrasonic screener superimposes high-frequency excitation of the cloth on the screening motion. This can help static, hygroscopic and agglomerating powders remain screenable. Achievable separation performance is sized from the material and trial data.

Operating principle
An ultrasonic transducer couples high-frequency vibration into the screen cloth. Deposits and agglomerates are loosened to help apertures remain open during demanding fine-screening duties. Cut size, throughput and cloth selection are confirmed from material data or trials.
Where this machine is used
Ultrasonic screening machine for pharma, food, cosmetics, metal-powder, ceramic and chemical plants – especially where fine, hygroscopic or agglomerating powders blind the mesh.

Frequently asked sizing questions
When is an ultrasonic screener useful?
It is assessed when very fine, static, hygroscopic or agglomerating powders quickly blind the mesh. Whether ultrasound helps depends on the actual material behaviour.
Can the achievable cut size be guaranteed in advance?
Not without reliable product data or a trial. Cut size and throughput are assessed from size distribution, moisture, bulk density and material behaviour, and become binding only in the project specification.
What information should be included in the enquiry?
Include the material name, safety or product data sheet, size distribution, target size, moisture, temperature, required throughput and cleaning requirements. For sensitive products, also state material-contact and hygiene requirements.
