Ultrasonic Vibrating Screen-DAHAN Vibration Machinery

Introduction of Ultrasonic Vibrating Screen

Ultrasonic vibrating screen is an additional ultrasonic system on the basis of ordinary vibrating screen，it consists of consisting of a generator and a probe that applies an ultrasonic frequency to a mesh screen,it has been designed to allow for difficult powders to be easily screened on sieve meshes. Not only does this increase the capacity of the product that is sieved but allows for accurate separation down to 20µm (#635mesh)。Screening accuracy can be increased more than 80%, capacity increased by 2 to 5 times.

Ultrasonic vibrating screen is mainly used to screen ultra-fine powder

Ultrasonic vibrating screen also be called as other name in different country, for example, sometimes will also named it as Ultrasonic Sieve; ultrasonic vibro sifter; ultra-sonic vibrating separator and so on.

Note: Our ultrasonic vibrating screen adopts a gate design, and the operator can decide the material screening time by himself.

Function of Ultrasonic Vibrating Screen

1. Ultrafine powder screening: Really solve the screening problems of the characteristics material of strong adsorption, adhesion, sticky, high static, high density, ultrafine powder, etc.

2. Solve the network blockage: convert 220V, 50Hz electric energy into 38KHz high frequency electric energy, input the ultrasonic transducer, and turn it into 38KHz mechanical vibration, so as to achieve the purpose of screening and cleaning the network, making it easy to screen fine powder Increasing the penetration rate and reducing the clogging of the screen.

3. Reduced costs: eliminates mesh damage normally associated with mechanical cleaning devices, increasing mesh life

Ultrasonic vibrating screen can prevent mesh blinding and blocking

Benefits of Ultrasonic Vibrating Screen

Suitable for Ultra-fine Powder

Solved the problem of the sieving of strong adsorption, free huddle, strong stickiness, high static, high density, ultrafine powder, etc.

Not Clog the Mesh

The vibration frequency of the ultrasonic vibrating screen is 360,000 times/minute, which effectively prevents the screen from clogging, and the materials that are difficult to screen hardly block the mesh.

Improve Efficiency

The accuracy of the sieve can be increased by more than 80% and the output is increased by 2-5 times.

Lower Cost

There is no need to add a screen cleaning device, except for the damage of the mesh usually associated with mechanical cleaning equipment, and increase the service life of the mesh.

Working Principle of Ultrasonic Vibrating Screen

Ultrasonic vibrating screen can input 220V, 50Hz or 110V, 60Hz electric energy into the ultrasonic transducer, and turn it into 36KHz mechanical vibration. Ultrasonic vibrating screen can input 220V, 50Hz or 110V, 60Hz electric energy into the ultrasonic transducer, and turn it into 36KHz mechanical vibration. The generated ultrasonic wave makes the screen mesh vibrate at a high frequency. The materials on the screen surface are superimposed with ultrasonic vibration while performing low-frequency rotational vibration, which can not only prevent mesh clogging, but also improve the output and product quality of the screening machine, making the ultrasonic vibrating screen easy to screen ultrafine powder.
