The ultrasonic vibrating screen converts 220V/50Hz or 110V/60Hz mains power into 38kHz high-frequency electrical energy, which is delivered to an ultrasonic transducer and transformed into 38kHz mechanical vibration to achieve high-efficiency sieving and mesh deblinding. Built on conventional vibrating screen architecture, this system introduces a low-amplitude, high-frequency ultrasonic mechanical wave onto the screen surface. Ultra-fine powder particles gain strong ultrasonic acceleration and remain suspended on the screen deck, which prevents mesh clogging caused by adhesion, friction and particle settling. It resolves long-standing sieving challenges for highly adsorptive, easily agglomerated, high-static, ultra-fine, high-density and low-specific-gravity materials, making ultra-fine powder sieving a stable, efficient process. It is particularly suitable for manufacturers producing high-quality fine powders.
Working Principle
The ultrasonic vibration wave applied to the screen mesh imparts significant ultrasonic acceleration to ultra-fine powder particles. This suppresses mesh clogging triggers including particle adhesion, friction, settling and wedging, and improves both sieving throughput and mesh cleaning efficiency.
Product Description
This ultrasonic vibrating screen converts 220V/50Hz or 110V/60Hz electrical power into 18kHz high-frequency energy, which is transmitted to the ultrasonic transducer and converted into 18kHz mechanical vibration for efficient sieving and mesh cleaning. Based on traditional vibrating screen design, the system adds a low-amplitude, high-frequency ultrasonic mechanical wave to the screen surface to enhance sieving performance for ultra-fine particles, making it ideal for users processing high-value fine powders.
As a derivative of the rotary vibrating screen, this model integrates an ultrasonic controller seamlessly with the screen body. Developed on years of rotary screen R&D and manufacturing experience, it superimposes a high-frequency, low-amplitude ultrasonic vibration onto the mesh. The strong ultrasonic acceleration keeps ultra-fine powder particles suspended on the screen deck, preventing clogging from adhesion, friction, particle settling and wedging. It addresses sieving difficulties with highly adsorptive, agglomeration-prone, high-static, ultra-fine, high-density and low-density materials, and is perfectly suited for high-quality fine powder production.

Ultrasonic Power Supply Unit
The ultrasonic power supply unit is the technical core of the system. It plays a critical role in eliminating mesh aperture clogging, enabling the vibrating screen to handle finer particle sizes, deliver higher sieving efficiency and cover a wider range of material applications.
Ultrasonic Transducer
Powered by the shared ultrasonic power supply, the mesh-cleaning transducer removes clogged particles from screen apertures through contact and relative movement between its radiating surface and the blocked mesh. It delivers fast, highly efficient cleaning with improved deblinding quality, and causes no alteration to aperture dimensions or damage to the screen wire surface. It is widely compatible with both test sieves and industrial production screen units.
