1.       Working principle

Ultrasonicsieving system consists of ultrasonic generator, energy converter and resonant ring. 

Ultrasonic generator produces highfrequency oscillation and energy converter turns it into high-frequencysinusoidal longitudinal shock wave. 

This shock wave gets to resonant ring to make it resonate. Then resonant ring puts oscillation transmissionto screen surface evenly. 

Materials on the surface will do low-frequency threedimensional vibration and ultrasonic vibration at the same time. This canprevent mesh clogging and improve yield and quality of screening

2.       Product feature

·Ultrasonic wave uses integrated circuit plate, fully obturated, digitalCPU control, specialized voyage plug: it can continue working for 12 ~ 24hours, there is no cooling process.

·Screening precision can be improved by 70%and handling capacity is 2 ~10 times more than the common screening machine. Itis particularly significant to materials which are difficult to screen such as Siliconcarbide powder, hard alloy powder, coffee powder.

·Sieving mesh can reach 600. It cancompletely self-clean, be easy to operate and maintain.

·It can really solve some difficult problems such as strong absorption, easyreunion, high static, high precision, high density, light proportion and so on.

·It can ensure that the characteristics of thematerials are unchanged.
