Ultrasonic Vibrating Separator for High Precision Powder Screening
Our ultrasonic vibrating separator is designed for accurate screening of fine powders and difficult-to-screen materials. The ultrasonic system helps prevent mesh clogging, improves screening efficiency, and maintains stable separation performance. Available with customized designs, factory direct prices, and professional solutions for different industries.
What Is an Ultrasonic Vibrating Separator?
Il setaccio vibrante a ultrasuoni combines the advantages of a vibrating screen and ultrasonic technology. The ultrasonic generator creates resonance with the screen frame, which is then transferred to the screen mesh and produces high-frequency vibration across the mesh surface.
This high-frequency vibration helps solve common screening problems with fine powders, including mesh clogging, material sticking, particle adhesion, agglomeration, static electricity, and low-density materials. The system can increase screening capacity by up to 10 times and improve production efficiency, while allowing separation down to 20 μm (#635 mesh).
Working Principle
Basic Vibration
Driven by a vibration motor, eccentric weights generate standard circular or linear vibration, causing material to disperse evenly across the screen surface.
Ultrasonic Vibration
An ultrasonic generator converts electrical energy into high-frequency vibration (typically 20–40 kHz), which is transmitted via a transducer to the screen mesh, inducing high-frequency, micron-level vibrations.
Anti-Clogging Principle
High-frequency vibration rapidly breaks up material agglomerates while causing particles at the mesh openings to “levitate.” This prevents fine powder from becoming lodged in the apertures due to static electricity or adhesion, thereby ensuring efficient material passage.
Structure of the Ultrasonic Vibrating Separator
Il ultrasonic vibrating sifter primarily consists of a vibrating motor, an ultrasonic generator, an ultrasonic transducer, a screen mesh, and a vibration-damping system.
Vibrating motor:Provides the fundamental vibration power; it must be matched to the equipment’s power requirements to ensure uniform material dispersion.
Ultrasonic generator: Outputs high-frequency electrical signals; it requires frequency stability (e.g., 20 kHz) and must feature overload protection.
Ultrasonic transducer: Converts electrical signals into mechanical vibrations; it must synchronize with the generator’s frequency and be mounted in direct contact with the screen mesh.
Screen mesh: Facilitates material classification; typically made of stainless steel to meet the standards of industries such as food processing and pharmaceuticals.
Vibration-damping system: Minimizes the impact of equipment vibration on the floor and frame; rubber springs are commonly used to reduce noise.
Two Types of Ultrasonic Vibrating Separators
Internal Space Frame vs. External Space Frame
1. Internal Type
The transducer is mounted at the bottom of the screen mesh.
Installation requires removing the screen frame and mesh.
Relatively low cost.
Used in the food and pharmaceutical industries.
2. External Type
The transducer is mounted outside the screen frame.
Installation and maintenance are quick and easy.
High cost.
Suitable for corrosive materials.
Features
1. High Precision
Il setaccio vibrante a ultrasuoni efficiently separates and screens fine particles with a precision of up to 0.01 mm, effectively enhancing product quality.
2. Wide Range of Applications
The ultrasonic vibrating screen is suitable for screening and separating a wide variety of granular materials—including solids, liquids, powders, and granules—offering broad applicability.
3. Environmentally Friendly
The ultrasonic vibrating screen generates no harmful substances during the screening process; it causes no environmental pollution and complies with modern environmental protection standards.
4. High Efficiency
The ultrasonic vibrating screen offers extremely high screening speeds; output can increase by up to 10 times, thereby reducing production costs.
5. Easy Maintenance
The ultrasonic vibrating screen features a simple structure that is easy to maintain and service; the extended service life of the screen mesh lowers operating costs.
6. Low Material Damage
High-frequency, low-amplitude vibration causes minimal damage to materials (especially crystals and fibers), preserving their original properties.
