What is the purpose of a dewatering screen? The dewatering screen is often used in coal preparation, ...
The ultrasonic vibrating sieve for fine powder is effective to prevent screen clogging, solving the screening problem of materials with strong adsorption, easy to reunite, static electricity and light specific gravity such as metal powder. The particle size grading of ultrasonic screener for dry powder can reach 20μm.
The ultrasonic vibrating screen adopts advanced intelligent ultrasonic vibration controller, which changes inadaptability and uncontrollability brought by single frequency, really realizing the organic combination of ultrasonic and vibrating screen, meeting and exceeding the level of international similar products in performance. Solve the screening problems of strong adsorption, easy reunite, high electrostatic, high fine, high density and light specific gravity, has superior performance. The screening accuracy of ultrasonic vibrating sieve 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.
The performance of ultrasonic separator is comparable to similar international products. AAREAL ultrasonic screening machines have been exported to the Japanese market for a long period of time and has been well received by foreign customers.
Working Principle of Ultrasonic Vibrating Sieve:
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 of ultrasonic separator 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. With ultrasonic screening system, the dry powder particle size can be classified to 25μm (600 mesh).
Features of Ultrasonic Vibrating Sieve:
1. High precision screening. The screening accuracy can be improved by 1~70%, and the output can be increased by 0.5~10 times.
2. Effectively prevent screen clogging. The service life of the screen is long.
3. Continuous operation and high energy conversion efficiency (meet the international standards for similar products).
4. It can screen particles over 20μm.
Ultrasonic Screening System of Ultrasonic Vibrating Sieve:
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.
Ultrasonic Control Power Supply of Ultrasonic Vibrating Sieve:
Power Supply: 220V 50Hz
Operating Frequency: 36KHz
Operating Mode: continuous/pulse
Environment Temperature: 0～45 ℃
Overall Dimensions: 300*390*200mm
Intensity Adjustment: 50～100%
Ultrasonic Transducer of Ultrasonic Vibrating Sieve:
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 Type Ultrasonic Transducer
Built-in Type Ultrasonic 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|
Different Kinds of Ultrasonic Screen Frames:
External Type Ultrasonic Screen Frame
External Type Ultrasonic Screen Frame with Multiple Transducer (2~3 pcs)
Built-in Type Ultrasonic Screen Frame
Rectangular Type Ultrasonic Screen Frame
