Ultrasonic sieve technology is used when a standard screen configuration does not perform well enough on fine or difficult products. The system supports the mesh with high-frequency vibration, reducing blinding and keeping the active screen area more available.
What ultrasonic support does in practice
With fine meshes, blinding often occurs: openings are partially or fully blocked by product particles. Capacity drops and separation becomes unstable.
Ultrasonic support helps limit this blockage by keeping the mesh in additional continuous motion. Especially with fine powders, this can create a much more consistent separation.
For which products it is useful
Ultrasonic systems are often used for very fine powders, metal powders, coatings, chemical raw materials and other products where mesh selection is critical or mesh blinding is likely.
Not every product needs it. With coarser or free-flowing materials, ultrasonic support often adds less value than with fine, cohesive streams.
Main advantages
The greatest benefit is usually higher net use of the mesh, more consistent quality and less downtime for cleaning or intervention.
Ultrasonic support can also make finer meshes practical in a process that would otherwise block too quickly.
- Lower risk of blinding with fine meshes.
- More stable separation over longer production runs.
- Ability to make finer specifications achievable.
Treat it as a process aid
Ultrasonic support is not a replacement for a good basic choice of machine, mesh and product feed. It works best when the rest of the process is already logically set up.
The technology should therefore always be assessed together with product testing, mesh selection and machine configuration.
