Ultrasonic Sieving Machine

Introduction of ultrasonic sieving machine

Ultrasonic sieving machine adds an ultrasonic blinding system to the sieving machine, which uses ultrasonic frequencies to vibrate the net. This prevents the holes from being clogged and makes it easier to screen the powder. The system can increase the screening capacity by up to 10 times, thereby increasing productivity, while allowing separation accuracy as low as 20 microns (#635 mesh).

The deblinding system can be installed on a new or existing vibrating screen for easy integration into your production line. Preventing the screen from being overloaded not only reduces production downtime, it also reduces the time required to clean the mesh.

Benefits of ultrasonic sieving machine

1. It has a better effect on materials that are difficult to screen, such as strong adsorption, easy agglomeration, high static electricity, high precision, high density, and light specific gravity.

2. Compared with ordinary sieving machine, the screening accuracy can be increased by 1-70%, and the output can be increased by 0.5-10 times.

3. It can be used in single layer or multiple layers, and a set of intelligent ultrasonic generator uses three transducers at the same time.

4. While achieving high-precision and high-mesh screening, it effectively controls the concentration of particle segments.

5. With self-cleaning function, when screening >500 mesh, there is no mesh clogging, no screening efficiency attenuation, and high signal uniformity.

6. The output waveband of the numerical control power supply is transmitted to the surface of the screen 360,000 times per minute through the transducer.

Working principle of ultrasonic sieving machine

Ultrasonic sieving machine converts 220V, 50Hz or 110V, 60Hz electrical energy into 18KHz high-frequency electrical energy, which is input into an ultrasonic transducer to turn it into 18KHz mechanical vibration. The materials are not only subjected to the force of the three-dimensional rotary vibrating screen during screening. The force that causes the material to make up and down, horizontal and inclined three-dimensional movements on the screen surface is also subjected to the high frequency and low amplitude force exerted on the screen surface by the ultrasonic system, so as to achieve the purpose of screening and cleaning.

Structure of ultrasonic sieving machine

The structural composition mainly includes:

1. Ultrasonic grid: It is composed of an external grid and a resonance ring.

2. Screen: suitable for 10 mesh-635 mesh

3. High-frequency connection cable: the cable used to connect the ultrasonic oscillator and the ultrasonic resonant power supply.

4. Ultrasonic resonance power supply: LCD display window, 38KHZ high frequency and high power ultrasonic resonance power supply. The built-in computer chip can automatically track the whole digital frequency according to the different states of the ultrasound, without manual adjustment, and the operation is convenient and simple. Long-time working oscillator has low heat output and stable working condition.

5. Oscillator: high-performance ultrasonic conversion device.

6. Connector: Aviation connection plug-in.
