Ultrasonic vibrating screen is to convert 220V, 50Hz or 110V, 60Hz electrical energy into 18KHz high frequency electrical energy, input ultrasonic transducer, turn it into 18KHz mechanical vibration, so as to achieve the purpose of efficient screening and net cleaning. Based on the traditional vibrating screen, a low amplitude and high frequency ultrasonic vibration wave (mechanical wave) is introduced into the screen to improve the screening performance of ultrafine particles. Especially suitable for high value-added fine split users. Ultrasonic vibrating screen is a kind of derivatives of vibration sieve, the organic combination of ultrasonic controller and vibrating screen together, after years of research and production of vibration sieve, on the basis of above the screen mesh superposition of a high frequency and low amplitude of ultrasonic vibration wave, superfine powder to accept huge ultrasonic acceleration, the material on the surface of the screen always stay suspended state, In order to inhibit adhesion, friction, flat drop, wedging and other blocking factors, so as to solve the strong adsorption, easy agglomeration, high static electricity, high precision, high density, light specific gravity and other screening problems, so that ultrafine powder screening is no longer difficult, especially suitable for high-quality, fine powder users.
