Ultrasonic Vibrating Sieve-DAHAN Vibration Machinery

Introduction of Ultrasonic Vibrating Sieve

Ultrasonic vibrating sieve uses an ultrasonic transducer to apply high-frequency vibration to the screen. The frequency of the vibration breaks the surface tension, making the screen effectively frictionless, preventing too large and small particles from clogging or blocking the screen. Our ultrasonic system can Installed on new and existing vibrating sieve and screening machines, it can screen on finer meshes (as low as 20 microns) without clogging or clogging the apertures, and the sieving rate is increased by 5-20 times , Suitable for fine powder with strong adsorption, easy to agglomerate, high static electricity, high precision, high density, light specific gravity and other characteristics.

Application of Ultrasonic Vibrating Sieve

1. Ultrafine powder screening: Ultrasonic vibrating sieve really solves the screening problems of materials with strong adsorption, adhesion, viscosity, high static electricity, high density, ultrafine powder and other characteristics.

2. Solve the blockage of the screen: change the vibration frequency of the ordinary screen machine, the vibration frequency is 36000 times/min, so that the vibration frequency of the material in the same unit time increases, thereby increasing the number of times the material passes through the screen holes at the same time, and the material is easier to Through the screen, improve the permeability, so as to achieve the purpose of screening and cleaning the screen.

3. Cost reduction: Due to the elimination of screen clogging, the product quality remains consistent throughout the production process, and there is no need to stop the machine to clean the screen, reducing the risk of downtime and reducing production costs.

4. Increase the output: Since the screen will not be blocked, the screen can be cleaned without stopping, and the output can be increased by 0.5-10 times.

Ultrasonic vibrating sieve has been widely used in the screening of fine powders such as flour, graphite powder, rubber powder, quartz sand powder, metal powder, powder coating, phosphor powder, etc.

Working Principle of Ultrasonic Vibrating Sieve

Ultrasonic vibrating sieve is a low-amplitude, high-frequency ultrasonic vibration wave (mechanical wave) installed on the screen of the traditional vibrating sieve. The ultra-fine powder accepts huge ultrasonic acceleration and improves the flatness of low-density powder in gravity settling (powder Light contact with the mesh port), slip effect, improve the retention or wedging of high-density metal in the mesh port, improve the adhesion effect of electrostatic powder, thereby improving the screening efficiency and screening quality, and make the surface of the screen The materials are always kept in a suspended state, thereby inhibiting the blocking factors such as adhesion, friction, flat drop, wedging, etc., and finally solved the screening problems of strong adsorption, easy agglomeration, high static electricity, high fineness, high density, and light specific gravity. To improve the sieving performance of ultra-fine particles.

Available Options

optional equipment

Ultrasonic vibrating sieve transducer plays an important role in the vibrating screen and is an indispensable part of the ultrasonic screening system. The installation of the transducer can be divided into two types: external type and built-in type.

Built-in ultrasonic vibrating sieve: the connector of the ultrasonic transducer is placed inside the sieve machine for connection, so that it can directly contact the material during work, and the cost is low. The price of the built-in system on the market is twice that of the external system.

External ultrasonic vibrating sieve: the ultrasonic transducer is installed outside the screen frame and extends to the edge of the grid, avoiding direct contact with the material, avoiding contamination of the material, in line with the hygiene standards of the food and pharmaceutical industries, low failure rate, and improved capacity.

In addition, our products can also be customized according to your requirements, such as the height of the screen machine, the length of the discharge port, the addition of dust removal ports, the addition of iron removers, material (carbon steel or stainless steel), the size of the feed port, airtight Sex and other special use environments and specific use conditions.

FAQ

Q: What is the use of an ultrasonic vibrating sieve?: A: allows for easier separation of bulk powders such as metal powders, paints, chemicals or food powders. An ultrasonic frequency is passed through to the sieve mesh, causing it to vibrate. This prevents blinding, or blockage, thereby letting particles pass through the mesh more easily.

Q: What is the difference between ultrasonic vibrating sieve and vibrating sieve?: A: Ultrasonic vibrating sieve is equipped with an ultrasonic anti-blind device on the basis of vibrating sieve, so the mesh with self-cleaning function is not blocked, and there is no need to add anti-blocking devices such as bouncing balls. The screening accuracy and output will be higher than that of vibrating sieve.

Q: What kind of materials is suitable for screening ultrasonic vibrating sieve?: A: Suitable for sieving 500 mesh high-precision, highly absorbent, sticky, and easily agglomerated powder materials, with self-cleaning function and no blocking of the net.

Q: What are the models of ultrasonic vibrating sieve?: A: Conventional models are 600mm in diameter, 800mm in diameter, 1000mm in diameter, 1200mm in diameter, 1500mm in diameter, etc. Special models can also be customized according to the requirements of different users.
