What Is an Ultrasonic Vibrating Screen?

The ultrasonic vibrating screen is a type of vibrating screen that incorporates an ultrasonic system into the standard rotary vibrating screen design. This system introduces a low-amplitude, high-frequency mechanical wave to the screen mesh; the resulting high-speed action keeps the material on the screen surface in a suspended state, thereby preventing mesh clogging caused by factors such as adhesion, friction, settling, and wedging.

How Does an Ultrasonic Vibrating Screen Work?

An ultrasonic vibrating screen introduces a low-amplitude, high-frequency ultrasonic vibration wave onto the screen mesh. It converts standard electrical power (220V/50Hz or 110V/60Hz) into 18kHz high-frequency electrical energy and feeds it into an ultrasonic transducer, which transforms it into 18kHz mechanical vibration. Driven by the ultrasonic generator, this vibration causes the screen frame to resonate and transmits the energy to the screen surface, inducing high-frequency vibration that enables rapid screening and prevents mesh blinding.

Features

The ultrasonic vibrating screen mitigates issues such as the “flat-fall” effect (where powder makes only light contact with the mesh openings) and sliding effects associated with low-density powders during gravity settling; it prevents high-density metal particles from becoming trapped or wedged in the mesh and reduces the adhesion of electrostatically charged powders, thereby enhancing both screening efficiency and quality.

1. Eliminates the need for anti-clogging devices like bouncing balls, extending the service life of the screen mesh.

2. Increases screening intensity by 1–70% and boosts throughput by up to 10 times.

3. Solves screening challenges associated with materials such as ultrafine powders, difficult-to-screen granules, and flocculent substances.

4. Prevents powder contamination caused by auxiliary components like bouncing balls.

5. Maintains consistent mesh aperture size, ensuring stable screening precision.

6. Breaks down agglomerated or adhered material, reduces the volume of oversize material (oversize residue), and minimizes the number of screening passes required.

Structure of the Ultrasonic Vibrating Screen

The ultrasonic vibrating screen features a compact and rational design, primarily consisting of an ultrasonic generator, a transducer, an ultrasonic screen frame, a vibration motor, and a base.

Ultrasonic generator

Converts electrical energy into high-frequency electrical signals.

Ultrasonic transducer

Converts the high-frequency electrical signals from the generator into high-frequency mechanical vibrations.

Ultrasonic screen frame

Can be configured as a single-layer or multi-layer unit depending on classification requirements; options include stainless steel woven mesh, polyurethane screens, and more.

Ultrasonic Vibrating Screen vs Rotary Vibrating Screen

Supports various non-standard customizations to meet diverse operating conditions.

1. Differences

The standard rotary vibrating sieve is a general-purpose circular vibrating screen that relies solely on motor vibration and rubber cleaning balls; it is suitable for materials with coarse to medium mesh sizes.

The ultrasonic rotary vibrating sieve is an upgraded version of the standard model; it incorporates a high-frequency ultrasonic vibration system specifically designed to overcome the challenges associated with screening ultra-fine powders.

2. Selection Recommendations

For materials ＜200 mesh that are free of static electricity, do not easily stick to the mesh, and when the budget is limited: choose the standard rotary vibrating sieve.

For materials ≥200 mesh—such as ultra-fine powders, metal powders, graphite, lithium battery raw materials, powders prone to agglomeration or static, or for high-capacity continuous production: the ultrasonic rotary vibrating sieve is the necessary choice.

How to Choose the Right Ultrasonic Vibrating Screen

When selecting a suitable ultrasonic vibrating screen, the following points should generally be considered:

Material Characteristics

Consider particle shape, density, flowability, abrasiveness, and whether the material is prone to agglomeration or static buildup.

Particle Size & Mesh Requirement

Determine the target particle size distribution and the required mesh size to ensure the desired screening accuracy.

Production Capacity

Select the appropriate screen diameter, deck configuration, and motor power based on your hourly processing capacity.

Industry Requirements

Choose suitable construction materials and surface finishes, such as 304 or 316L stainless steel, to comply with food, pharmaceutical, chemical, or battery industry standards.

FAQs

An Ultrasonic Vibrating Screen superimposes 18~40kHz high-frequency ultrasonic micro-vibration on the ordinary three-dimensional vibration to eliminate screen mesh blocking through resonance, while ordinary rotary vibrating screens only rely on bouncing balls for mechanical mesh cleaning.

Ultra-fine powders above 200 mesh, electrostatic-prone, agglomerating and light micro-powders, such as lithium battery materials, graphite, metal powders, pharmaceutical micro-powders, silicon carbide, etc.

It addresses four major pain points in ultra-fine screening: mesh wedging blockage, electrostatic adhesion to mesh, powder agglomeration and poor stratification, and low output at high mesh counts.

There is no continuous impact on the mesh from bouncing balls; only mild high-frequency resonance is applied, which greatly reduces wear of high-mesh stainless steel screen cloth.

Yes. Ultrasonic vibration reduces particle adhesion, eliminates mesh clogging and improves material flowability, thus boosting screening efficiency.

Regularly inspect the wiring of transducers and the working status of ultrasonic generators. Frequent shutdowns for manual mesh cleaning are unnecessary, and the replacement cycle of screen cloth is greatly extended.
