What is an ultrasonic screen?

Ultrasonic screen is an ultrasonic system added on the basis of ordinary vibrating screen, applying ultrasonic frequency to the screen, it can separate 20m (#635 mesh) fine powder without any blocking or blinding of the aperture. It also increases throughput and reduces cleaning times.

Compared with ordinary vibrating screen, the screening accuracy is increased by 1-70%, and the output can be increased by 0.5-10 times. It solves the problem of strong adsorption, static electricity, strong viscosity and high density, and solves the problem of ultrafine powder screening. At present, it has been widely used in the screening of fine powders such as flour, graphite powder, rubber powder, quartz sand powder, metal powder, powder coating and phosphor powder.

Screens for The Use With Ultrasonic

Benefits of ultrasonic screener

Ultrasonic screen makes it easier to separate bulk powders such as metal powders, paints, chemicals or food powders. Ultrasonic frequencies pass through the screen, causing it to vibrate, which prevents blinding or clogging, allowing particles to pass through the mesh more easily.

1. Ultrafine powder screening: It really solves the screening problems of materials with strong adsorption, adhesion, viscosity, high static electricity, high density, ultrafine powder and other characteristics.

2. Solve the blockage of the screen: change the vibration frequency of the ordinary screen machine, the vibration frequency is 36000 times/min, so that the vibration frequency of the material in the same unit time increases, thereby increasing the number of times the material passes through the screen holes at the same time, and the material is easier to Through the screen, improve the permeability, so as to achieve the purpose of screening and cleaning the screen.

3. Cost reduction: Due to the elimination of screen clogging, the product quality remains consistent throughout the production process, and there is no need to stop the machine to clean the screen, reducing the risk of downtime and reducing production costs.

4. Increase the output: Since the screen will not be blocked, the screen can be cleaned without stopping, and the output can be increased by 0.5-10 times.

Application of Ultrasonic Screen

Ultrasonic screen has a better effect on materials that are difficult to sieve such as strong adsorption, easy agglomeration, high static electricity, high fineness, high density, and light specific gravity. It is suitable for 400 mesh, 500 mesh and 600 mesh fine materials, such as graphite powder, Diamond, glass powder, silica-alumina powder, slurry, white latex, alumina, quartz sand, lithium battery cathode material, metal powder, phosphor powder, titanium powder, trace mineral powder, sulfur powder, high nickel ternary cathode material, ring Oxygen powder, traditional Chinese medicine powder, catalyst, lithium battery powder, stainless steel metal powder, chili powder, diamond, matcha powder, etc.

How does Ultrasonic Screen work?

Ultrasonic screen is an ultrasonic deblinding system added on the basis of ordinary vibrating screen. It can input 220V, 50Hz or 110V, 60Hz electric energy into the ultrasonic transducer, and convert it into 36KHz mechanical vibration. High-frequency vibration, the vibration frequency can reach 36,000 times per second, which can make the fine powder material form a micro-suspended state on the screen, and can pass through the screen faster without generating static electricity and sticking to the screen. At the same time, it achieves the effect of screening and cleaning the screen.

Benefits of ultrasonic screen


Suitable for sieving of 20-300μm mesh

The high-frequency vibration makes the fine materials in contact with the screen pass through the screen quickly, and the penetration rate of the screen is improved. Our ultrasonic screening systems enable you to screen powders more efficiently with separation cuts from 20 µm to approx. The screening accuracy can be improved by 1- 70%.

Prevent mesh clogging

The ultrasonic system applies a high-frequency vibration to the sieve mesh. The frequency of the vibration breaks the surface tension, making the stainless-steel mesh effectively friction-free and preventing oversized and undersized particles from blinding or blocking the mesh screen.

Increase throughput

Ultrasonic sieving increases the sieving capacity by 10 times by making the powder pass through the sieve holes faster.

Upgrade existing systems

Simple retrofit solution for all new and existing shakers and screening machines.

Single/Multilayer Screening

Provides up to 5 levels of classification in one operation, and one or more ultrasonic transducers can be added to one screen to enhance the screening effect.

Reduce production downtime

Preventing clogging while reducing the time it takes to clean the screen, the frictionless system eliminates damage caused by mechanical deblinding systems.

Structure of Ultrasonic Screen

Ultrasonic screen model

1. Ultrasonic transducer: This structure is the characteristic structure of the ultrasonic vibrating screen, which has the function of converting low-frequency electric energy into high-frequency and low-amplitude ultrasonic waves.

2. Ultrasonic special network frame: This network frame structure is equipped with a resonance ring to convert the ultrasonic wave into a mechanical wave with high vibration frequency and low amplitude, and then transmit it to the surface of the screen. Using a special double-ring structure, it will give full play to the ultrasonic effect after measurement and design, and reasonably distribute the amplitude in the entire area of the screen, so that the ultrasonic energy can be evenly transmitted on the entire screen surface.

3. Ultrasonic power supply: This structure controls the output power and frequency of ultrasonic waves can be adjusted.

4. Screen, screen frame, vibrator, and base: The screen is woven, suitable for 10 mesh to 635 mesh, and the structure of the screen frame, vibrator, and base is similar to that of an ordinary screen.


Built-in and external ultrasonic screens

Built-in ultrasonic transducer: The ultrasonic transducer joint is placed in the middle of the grid of the ultrasonic screen, which can directly contact the material during operation, and the cost is low. At present, the price of the built-in system on the market is twice as low as that of the external system.

External ultrasonic transducer: The ultrasonic transducer is installed outside the screen frame and extends to the edge of the mesh frame. Because it avoids direct contact with materials and avoids contamination of materials, it meets the hygiene standards of the food and pharmaceutical industries, and the failure rate is low and improves. capacity.

ultrasonic transducers

Ultrasonic screens allow simultaneous excitation of multiple ultrasonic transducers using a single generator. Due to the change in frequency, even screens with different resonance characteristics can be excited simultaneously.

1.For large screen frames, a single large or multiple waveguide rings can be processed using multiple ultrasonic transducers excited by one generator.

2.Even individual screen frames, for example in screening machines with two or more screen decks, can be activated simultaneously.
