The screening solution for gentle ultra-fine screening

The ultrasonic screening system

The pulsation process developed by Ebbecke Verfahrenstechnik AG in combination with a specially designed plansifter screening system enables the gentle contract screening of even the finest powders that are difficult to screen. Grain destruction, which occurs with conventional ultrasonic processes, especially with platelet-shaped powders, is significantly reduced. The system with a closed vibrating dosing chute allows infinitely variable adjustment of the inclination, speed of the planar excitation and intensity of the ultrasonic pulsation.

Screening for specialized applications

Areas of application

Sieving is used in a variety of special applications. These include the precise separation of platelet-shaped pigment particles, such as those found in paints or coatings. Particles with a porous surface structure can also be reliably processed, where shape and texture pose a particular challenge. Even products with a low bulk density can be efficiently separated using adapted screening technology without any loss of material. For materials that tend to agglomerate, screening offers a way of breaking up clumps and ensuring a uniform particle size. In addition, carrying out the process in a protective gas atmosphere enables sensitive or reactive materials to be processed gently, thereby preserving their quality and stability.
