This machine a high-precision fine powder sieving machinery, its low noise, high efficiency, fast mesh change takes 3-5 minutes, fully closed structure, suitable for particle, powder, mucus and other materials screening and filtering. Rotary vibration sieve is made of upright motor as vibration source, with eccentric weights installed at the upper and lower ends of the motor, which transforms the rotary motion of the motor into three-dimensional motion of horizontal, vertical and inclined, and then transmits this motion to the sieve surface. Adjusting the phase angle of the upper and lower ends can change the trajectory of the material on the screen surface.
