Ultrasonic vibrating screen is an efficient screening equipment that adds an ultrasonic system to a regular vibrating screen.
Its working principle is to convert 220V, 50Hz or 110V, 60Hz electrical energy into 18KHz high-frequency electrical energy, input it into an ultrasonic transducer, and convert it into 18KHz mechanical vibration, thereby achieving the goal of efficient screening and net cleaning.
Ultrasonic vibrating screen has many advantages:
Fine screening: It can solve the screening problems of fine and micro powder materials such as high static electricity, easy agglomeration, strong adsorption, and light density. The screening accuracy can be improved by 1-100%, and the output can be increased by 0.5-10 times.
Strong self-cleaning ability: A high-frequency, low amplitude ultrasonic vibration wave is superimposed on the sieve, causing the ultrafine powder to receive a huge ultrasonic acceleration, thereby suppressing factors such as adhesion, friction, flattening, and wedging, and improving screening efficiency and cleaning effect.
Wide applicability: Suitable for various types of materials, including food, medicine, chemicals, metal powders, etc.
Its main structure usually includes screening frame, screen mesh, ultrasonic system, vibration motor and other parts.
In practical applications, ultrasonic vibrating screens are widely used in the following fields:
Pharmaceutical industry: fine screening of traditional Chinese medicine powder, western medicine powder, active pharmaceutical ingredients, etc.
Chemical industry: used for screening various chemical raw materials, coatings, pigments, etc.
Food industry: screening and grading of powdered sugar, flour, seasoning powder, etc.
For example, in the pharmaceutical industry, ultrasonic vibrating screens can ensure the accuracy and purity of screening for pharmaceutical raw materials with certain particle size requirements, thereby ensuring the quality of the drugs. In the chemical industry, for powders that are prone to clumping or have static electricity, ultrasonic vibrating screens can effectively solve the problem of clogging during screening and improve production efficiency.
When choosing an ultrasonic vibrating screen, the following aspects need to be considered:
The characteristics of screened materials include particle size, humidity, viscosity, etc.
Screening accuracy and yield requirements.
Material and quality of equipment: to adapt to different working environments and material characteristics.
The manufacturer's reputation and after-sales service.
In short, ultrasonic vibrating screens play an important role in material screening in many industries due to their advantages, providing strong support for improving product quality and production efficiency.
