DH series ultrasonic fine vibration screen is a high-precision and high-stability ultrasonic vibration screening machine developed by Ningbo Everses, which introduced German technology.

Product Introduction
DH series ultrasonic fine vibration screen is a high-precision and high-stability ultrasonic vibration screening machine developed by Ningbo Luoshang with German technology. It uses the intelligent ultrasonic controller designed by Professor Cui of Shanghai Jiao Tong University, and is assembled with imported original components that are finely tuned and combined, changing the non-adaptability and non-adjustability brought about by a single frequency, and truly achieving the organic combination of CNC and vibration screening. Its performance level reaches and surpasses that of international similar products, completely surpassing domestic products!
DH series ultrasonic fine vibration screen solves the screening difficulties of strong adhesion, easy agglomeration, high static electricity, high fineness, high density, and low bulk density, and has outstanding performance! It achieves a great breakthrough in performance.
Screening accuracy of the DH series ultrasonic fine vibration screen can be improved by 1-100%, and the output can be increased by 1-20 times. It truly meets the industrial production needs above 600 mesh!
Ultrasonic fine vibration screening instrument can be widely used in industries such as pharmaceuticals, metallurgy, chemical industry, mineral processing, and food.

Working principle
Ultrasonic fine vibration screen consists of an ultrasonic generator, transducer, resonance ring, resonant screen frame, and vibration platform. For better performance, please use it with matching equipment and do not mix it with other ultrasonic devices.
High-frequency electrical signal generated by the ultrasonic generator is converted into a high-frequency sinusoidal longitudinal oscillation wave by the transducer. These oscillation waves are transmitted to the resonance ring to make it resonate. The resonance ring then uniformly conducts the high-frequency vibration to the entire screen surface. While the material is vibrating at low frequency on the screen, a high-frequency ultrasonic vibration is superimposed to solve the problem of material blockage and improve the screening accuracy and efficiency.
