   Product Readme

Ultrasonic Separators allows separations of light powders with meshes ranging from 0,250 mm to 0,025 mm (25 micron).
Some powders, due to their granulometry, light bulk density and physical features, can not be sieved only with the mechanical movement of the separator. The Ultrasonic system allows the sieving thanks to the creation of an additional ultrasonic frequency vibration straight on the wire of the sieving mesh.
The ultrasonic frequency is applied to the sieve mesh via an acoustically developed transducer. This breaks down the surface tension, effectively making the stainless steel wires friction free and preventing particles, both slightly greater and smaller than the mesh, from blinding or blocking it. Screen blinding or blocking is a common problem in the sieving of difficult powders on screens of 500 micron and below. It occurs when either one or a combination of particles sits on or in an aperture of the mesh and stay there, or particles adhere to the mesh wires preventing other particles from passing through these openings. This is particularly common with sticky powders or materials that contain a large number of particles of a size similar to that of the apertures of the mesh. When blocking occurs, the useful screening area is reduced and, therefore, capacity drops.
Ultrasonic sieving device eliminates blinding and blocking of the mesh.

ADVANTAGES

- Productivity:
sieve on finer meshes (as low as 25 m) and obtain a better quality final product. Better sieving results are reached combining mechanical and ultrasonic vibrations
- Performance:
higher throughputs and screening efficiency, even for materials which are difficult to screen;
increase your sieving capacities up to 10 times by enabling powders to pass through screens faster by reducing screen overload and frequency of mesh cleaning.
- Maintenance:
prevent blinding of fine mesh, keep constantly clean the screening surface and avoid screen clogging;
guarantee a longer screen life;
eliminate mesh damage caused by mechanical deblinding systems.
- Set Up
the automatic frequency control selects the right frequency.
