 Product Introduction

1. The ultrasonic vibrating sieve, also known as an ultrasonic vibrating screen or ultrasonic separator, is a high-frequency vibrating screen used to separate fine powders or materials into different particle sizes. It utilizes ultrasonic vibrations to enhance the screening efficiency and improve the accuracy of particle separation. Here is some information about ultrasonic vibrating sieves:

Working Principle:

2. The ultrasonic vibrating sieve operates by converting electrical energy into high-frequency mechanical vibrations. These vibrations are generated by an ultrasonic transducer, which is mounted on the screen frame or directly connected to the screen surface. The transducer generates ultrasonic waves that are transmitted through the screen mesh, causing the screen to vibrate at high frequency. The ultrasonic waves help break the static bond between particles and the screen surface, preventing clogging and ensuring efficient separation of fine materials.

 Comment & FAQ

Q1: How does an ultrasonic vibration sieve work?

A: An ultrasonic vibration sieve consists of a vibrating screen mesh, an ultrasonic generator, and transducers. The generator produces high-frequency electrical signals, which are converted into ultrasonic waves by the transducers. These ultrasonic waves are then applied to the screen mesh, causing it to vibrate at high speed. The ultrasonic vibrations help to break the static friction between particles and the screen surface, improving the sieving efficiency and preventing clogging.

Q2: What types of materials can be sieved using an ultrasonic vibration sieve?

A: Ultrasonic vibration sieves are mainly used for micro powders, granules. They are suitable for applications in various industries, such as pharmaceuticals, chemicals, food processing, ceramics, metallurgy, and minerals. The sieves are particularly effective for fine and difficult-to-screen materials.

Q3: Can ultrasonic vibration sieves be used for wet materials?

A: Yes, ultrasonic vibration sieves can be used for wet materials. They are designed to handle both dry and wet sieving applications. Special considerations may be required for wet sieving, such as the use of waterproof screens and ensuring proper drainage of the liquid. Our ultrasonic vibrating sieve has two structure, one is the built-in ultrasonic transducer (Mainly used for ultra micro powder), the other is external ultrasonic transducer, it could be with better waterproof performance for wet sieving.  

Q4: How do I control the ultrasonic vibrations in the sieve?

A: Ultrasonic vibration sieves are equipped with control panels or interfaces that allow users to adjust and control the intensity and frequency of the ultrasonic vibrations. Users can typically adjust parameters such as power level, amplitude, and frequency to optimize the sieving process for different materials and particle sizes.

Q5: How do I clean and maintain an ultrasonic vibration sieve?

A: Cleaning and maintenance procedures for ultrasonic vibration sieves are similar to those of traditional vibrating sieves. Regular cleaning is essential to prevent screen blinding and maintain optimal performance. The ultrasonic transducers should be cleaned periodically to remove any buildup or contaminants. It is important to follow the manufacturer's guidelines and recommendations for cleaning and maintenance to ensure longevity and reliable operation.

Q6: Can I retrofit my existing vibrating sieve with ultrasonic technology?

A: Yes, it is supported well to retrofit an existing vibrating sieve with ultrasonic system. Retrofitting kits are available that can be installed on standard vibrating sieves to add the ultrasonic capabilities. This allows users to upgrade their equipment without having to invest in a completely new ultrasonic vibration sieve.

 Anti-blocking Device

1. Ball Cleaning System: This system utilizes bouncing rubber balls placed underneath the screen mesh. As the sieve vibrates, the balls continuously strike the underside of the screen, dislodging any particles that may be trapped in the openings. This bouncing action helps to prevent clogging and ensures the smooth flow of material through the sieve.

2. Ultrasonic Cleaning System: Ultrasonic vibration can also be used as a cleaning mechanism in rotary vibrating sieves. Ultrasonic transducers are mounted on the screen surface, emitting high-frequency vibrations that create microscopic bubbles in the liquid or slurry being screened. These bubbles implode near the screen surface, effectively dislodging particles and preventing clogging.

Both of these cleaning devices are effective in reducing screen clogging and improving the efficiency of rotary vibrating sieves. The selection of the appropriate cleaning device depends on factors such as the type of material being screened, the level of clogging anticipated, and specific application requirements. Manufacturers and suppliers of rotary vibrating sieves can provide guidance on the best anti-clogging device for your specific needs.
