Ultrasonic vibrating screen is an efficient and precise screening equipment that adds an ultrasonic system to a regular vibrating screen.
1、 Working principle
Ultrasonic vibrating screen converts 220V, 50Hz or 110V, 60Hz electrical energy into 18KHz high-frequency electrical energy, inputs it into an ultrasonic transducer, and converts it into 18KHz mechanical vibration, thereby achieving efficient screening and cleaning of the mesh.
2、 Main features
High screening accuracy
Due to the effect of ultrasound, it can effectively solve screening problems such as strong adsorption, easy agglomeration, high static electricity, high precision, high density, and light density. The screening accuracy can be improved by 1-70%, and the yield can be increased by 0.5-10 times.
It can accurately screen up to 500 mesh (25 μ m) or even higher mesh numbers.
Good cleaning effect
Ultrasonic waves introduce a low amplitude, high-frequency ultrasonic vibration wave on the screen, which can effectively break the adhesion between the material and the screen, achieve rapid cleaning, reduce screen clogging, and improve screening efficiency.
Wide range of applications
Suitable for screening various fine powders, particles, slurries and other materials, such as food, medicine, chemical, metallurgical, ceramic and other industries.
Easy to operate
3、 Structural composition
It mainly consists of a screening box, a mesh frame, an ultrasonic system, a vibration motor, and shock-absorbing springs.
Screening box
Made of high-quality stainless steel material, it has the characteristics of corrosion resistance, high temperature resistance, and high strength.
Reasonable design, good sealing, can effectively prevent dust from flying.
grid frame
Usually, a separate structure of mother and child mesh is adopted, with the mother mesh supporting the fine mesh, which prolongs its lifespan.
Different mesh sizes can be replaced according to different screening requirements.
Ultrasonic System
Including ultrasonic generators, transducers, resonant rings, etc.
The ultrasonic generator generates high-frequency electrical energy, which is converted into mechanical vibration through a transducer and then transmitted to the screen through a resonant ring.
Vibration Motor
Provide a vibration source for the equipment to generate high-frequency vibration on the screen surface, promoting material screening.
Different power vibration motors can be selected according to different screening needs.

4、 Precautions for use
installation and debugging
The equipment should be installed on a horizontal foundation to ensure that the four supporting feet are evenly stressed.
After installation, no-load debugging should be carried out to check the operation of the equipment, adjust the eccentric block angle of the vibration motor, and achieve the best screening effect of the equipment.
Operation and Maintenance
Operators should be familiar with the operating procedures of the equipment and strictly follow the operating procedures.
Regularly maintain and upkeep the equipment, check the wear of the screen mesh, and replace damaged screens in a timely manner.
Keep the equipment clean and avoid material accumulation inside the equipment.
Safety Precautions
During the operation of the equipment, it is strictly prohibited to open the screen box cover to avoid danger.
When the equipment malfunctions, it should be stopped immediately for inspection and troubleshooting before continuing to operate.
