Overview of Ultrasonic Separator:
Ultrasonic separator is also called ultrasonic vibrating screen, ultrasonic vibrating sieve, ultrasonic sieve deblinding system, ultrasonic screener, ultrasonic screen separator etc.
Ultrasonic vibrating screen solves the screening problem of materials with strong adsorption, easy agglomeration, strong viscosity, high static electricity, high density, super fine powder etc. The screening accuracy can be increased by 1~100%, and the output can be increased by 1~10 times, really meeting the industrialization production of 100 mesh ~500 mesh and above.
It can be installed in various kinds of screening machines, such as ultrasonic test sieve shaker, ultrasonic round separator, ultrasonic rectangular separator, ultrasonic tumbler screen, ultrasonic airflow centrifugal screen, ultrasonic gyratory screen and so on.
Working Principle of Ultrasonic Separator:
The ultrasonic screening system consists of ultrasonic control power supply, ultrasonic vibrator (ultrasonic transducer) and screen mesh with energy conduction ring.
The ultrasonic screening system uses high frequency electronic frequency to convert into mechanical kinetic energy through the transducer, which makes the screen produce vibration of high frequency and low amplitude, and the vibration is transmitted through the energy conduction ring rapidly to the screen. This ultrasonic vibration can be conducted by the wire mesh of the screen, in this way, each wire mesh is in the high-frequency vibration, so it can prevent the blockage of small mesh, ensure that the screen always keep the maximum aperture ratio in the screening process. And it can also improve the liquidity of the material and make it smoothly go through the mesh screen, exactly solving the screening problems of strong adsorption, easy reunite, high electrostatic, high fine, high density and light specific gravity. Dry powder particle size can be classified to 25μm (600 mesh).
Features of Ultrasonic Separator:
1. While achieving high accuracy and high mesh screening, control the narrow range of particle size.
2. It can be used with single layer and multi-layer. A smart ultrasonic generator can use three transducers at the same time.
3. Complete screen self-cleaning function. More than 500 mesh screening, no mesh blockage, no screening efficiency attenuation.
4. It can exactly solve the screening problems of strong adsorption, easy reunite, high electrostatic, high fine, high density and light specific gravity etc.
5. Ensure that the properties of the treated material remain unchanged.
6. The screening accuracy can be increased by 1~100%, and the output can be increased by 1~10 times.
Ultrasonic Screening System for Ultrasonic Separator:
The core technical components of ultrasonic vibrating screen is the ultrasonic screening system, and the ultrasonic screening system is divided into ultrasonic power supply and transducer.
(1) Ultrasonic Control Power Supply:
Power Supply: 220V 50Hz or 110V 60HZ
Working Frequency: 36KHZ
Operating Mode: continuous/pulse
Intensity Adjustment: 50～100%
(2) Ultrasonic Transducer:
The ultrasonic transducer is very important in the ultrasonic system. Different transducers have quite different prices. The ultrasonic transducers imported from Switzerland are more expensive. But the quality is very good.
There are two kinds of installation form of ultrasonic transducer. One is built-in transducer design, and the other is the external transducer design.
External Transducer Built-in Transducer
Differences in Design:
| Item Compared | External Transducer | Built-in Transducer |
| Installing Form | The external transducer is mounted outside the screen frame and the extending part is at the edge of the grid | The built-in transducer is fixed directly in the middle of the grid |
| Cleaning Method | Disassembly and cleaning are relatively convenient | When cleaning, people need to remove the screen frame, and then lift the grid to clean up |
| Applicable Materials | The external transducer does not have direct contact with the material, so it can protect the transducer effectively, improving the service life, screening accuracy and output | The built-in transducer will contact the material during use. For some conductive and corrosive materials, contact with the transducer will reduce the service life, and also affect the output frequency, thereby reduce the precision and output. |
Differences in Use:
| Item Compared | External Transducer | Built-in Transducer |
| Cost | The market price is about double the price of a built- in transducer | |
| Maintenance | The external installation of the transducer greatly reduces the maintenance difficulty | The built-in installation of the transducer will make maintenance more difficult |
| Service Life | For the installation of external support device and quick clamping device, it can ensure the stability of the transducer external interface effectively, and make sure the friction between the transducer cable and the screen frame is reduced to the minimum in the operation of the screen, so as to prolong the service life of the transducer | Because of the long time contact with the material and vibration with the vibrating screen, thereby reducing the service life of the transducer |
| Effect | The external transducer does not have any effect on special materials because it avoids the direct contact with materials |
