Vibrating Sifter

Introduction of vibrating sifter

Vibrating sifter is a common type of fine screening equipment, suitable for sieving powders and particles, and can also be used to filter liquids. 0-500 mesh dry, wet, fine, coarse, large and small specific gravity powders and particles can be easily screened, within 5 microns The liquid material can be easily filtered.

Benefits of vibrating sifter

1. Wide screening range, can screen powder particles within 500 meshes, filter 5 micron slurry materials, each vibrating sifter can choose 1-5 layers of screens, which can carry out 2 to 6 levels of sorting and filtering at the same time.

2. It does not block the screen, and has a bouncing ball cleaning device. It can achieve the purpose of cleaning the screen by continuously hitting the screen. There is no blocking of the screen. All incoming materials are automatically discharged, and there is no storage in the machine, which improves the screening output and efficiency.

3. No dust pollution, fully sealed structure, no dust flying, no liquid leakage during the screening process.

4. Long service life and good maintenance: The rotating vibrating screen frame adopts the structure of the mother and the second screen to ensure the flatness and tension of the screen, preventing the material from impacting and collapsing the working net, and also preventing the bouncing ball on the screen from hitting the working net. , It only takes 3-5 minutes to change the screen, easy to operate and easy to clean.

Working principle of vibrating sifter

Vibrating sifter uses a vertical motor as the excitation source. The upper and lower ends of the motor are equipped with eccentric weights, which can convert the rotation of the motor into a horizontal, vertical, and inclined three-dimensional motion, and then transfer this motion to the screen Surface, the material on the screen surface expands and involutes outward movement. By adjusting the phase angle of the eccentric weight at the upper and lower ends of the motor, the movement trajectory of the material on the screen surface can be changed, so that the material can be finely screened. , Probability screening, etc.

Structure of vibrating sifter

Vibrating sifter is mainly composed of feed port, dust cover, discharge port, beam ring, screen, counterweight, upper weight, vibrating body, vibration motor, spring, lower weight, base and other parts.

Dust cover: prevent the material from spreading out, and also protect the external dust from entering, thereby contaminating the screening material.

Beam ring: used to fix the screen frame in the middle of the screen body.

Upper weight and lower weight: Changing the phase angle of the upper and lower weights of the vibration motor can change the movement trajectory and residence time of the material on the screen.

Spring: vibration damping and sound insulation.

Frame: Support the entire vibrating screen to keep its work stable.
