Ultrasonic Separator

 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
