Ultrasonic shaker on the basis of the original vibration sieve, sieve additional ultrasonic vibration analyzer, mechanical waves generated by the instrument, make superfine powder accept the tremendous acceleration of ultrasound, thereby inhibiting the adhesion, friction, flat down, wedging network factors, such as blocking to improve screening efficiency and clear net benefit. The characteristics of the ultrasonic vibration sieve characteristics of the device can effectively improve the low-density powder in the gravity settling level drop (powder and network Kouqing contact), the slip effect, improve the high-density metal stuck in the net mouth or wedge, to improve with adhesion effects of electrostatic powder, thereby improving the screening efficiency and screening quality. Using the screening by the rate of general increased by 50% -100% higher than that without ultrasonic vibration sieve and in some cases increase the pass rate of 400 percent. (1) reduce or no clear net time; (2) does not produce the pollution of the bouncing balls and other aids powder; (3) Keep the size of the mesh to stabilize the screening accuracy; (4) decomposition of the adhesion material, reduce screen on the matter; (5), high screening efficiency;
