It 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, the generated power ultrasonic makes the screen for high frequency vibration. The material on the screen is in the low-frequency rotary vibration movement at the same time, superimposed on the ultrasonic vibration, not only can prevent mesh clogging, but also can make the screen machine to improve the output and quality, so as to achieve the purpose of efficient screening and net cleaning, so that the ultra-fine powder screening into easy. 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.
