What Are The Important Characteristics And Advantages Of Ultrasonic Vibration Screen in Structure, Technology And Function?

The ultrasonic vibrating screen is a derivative product of the three-dimensional vibrating screen. Its principle is to combine the ultrasonic generator with the rotary vibrating screen, convert the 220V, 50Hz or 110V, 60Hz electrical energy into the 18KHz high-frequency electrical energy, input the ultrasonic transducer, and turn it into the 18KHz mechanical vibration, so that the screen surface produces the invisible supersonic vibration, so as to suppress the adhesion, friction, wedging and other blocking factors, and then achieve the purpose of screening and cleaning, Make it easy to screen ultra-fine powder.

It is especially suitable for users with high-quality and fine powder. This system introduces a low amplitude and high frequency ultrasonic vibration wave (mechanical wave) on the screen based on the traditional vibrating screen to improve the screening performance of ultra-fine powder. It is especially suitable for users engaged in value-added fine powder.

Features of ultrasonic vibrating screen:

1. Improve the leveling (light contact between powder and mesh) slip effect of low density powder in gravity sedimentation, improve the retention or wedging of high density metal in mesh, and improve the adhesion effect of electrostatic powder, so as to improve screening efficiency and screening quality. In terms of screening passing rate, the passing rate is generally 50% - 400% higher than that of ordinary rotary vibrating screen;

2. It is applicable to screen separation of powder from 20 μ m to 300 μ m to speed up the separation of agglomerates, high static electricity, high precision, high density, light specific gravity, and adsorbed materials, thus increasing its sieve weight;

3. Decomposition of adherent substances and reduction of materials on the screen increase the screening rate by 5-20 times compared with the vibrating screen without ultrasonic;

4. There is no need to add any other screen cleaning device, which has self-cleaning function, and the mesh is not blocked, thus extending the service life of the screen;

5. It can clearly separate fine particles with a diameter close to each other, with high screening accuracy;

6. It does not change the characteristics of screening materials, especially the ability and scope of screening new materials. There are technologies that other screening machines cannot achieve;

7. The screening accuracy can be increased by 1 - 70%, and the output can be increased by 0.5 - 10 times.

The high-frequency electricity generated by the power supply of the ultrasonic vibrating screen is converted into high-frequency sinusoidal longitudinal vibration waves through the transducer. These vibration waves are transmitted to the resonator to make the resonator resonate, and then the vibration is uniformly transmitted to the screen surface by the resonator. The materials on the screen are subject to low-frequency three-dimensional vibration and ultrasonic vibration, which can not only prevent mesh clogging, but also improve screening output and accuracy.
