Rotary Vibrating Sieve Principles

The rotary vibrating sieve uses an upright motor as the source of vibration, and it is equipped eccentricity hammer on both sides of the motor. Adjust the phase angle on both sides of the top and bottom to change the movement orbits of the surface screen. It can be equipped with a screen cloth cleaning device to avoid clogging effectively. The vertical and horizontal movement of the machine, and the track of materials on the screen can be controlled by adjusting the angle of the two eccentric weights.    

Our circular vibratory sieve can sift, de-dust, and classify a wide range of powders, eliminating any unwanted solids and ensuring consistent and reliable processing. We can supply our screeners in a wide range of single or multi-deck configurations, for batch or continuous processing.

How Does a Rotary Vibrating Sieve Work?

The working principle of a rotary vibrating sieve involves the following steps:

Step 1: Material Feeding

 The material to be screened is fed into the center of the sieve through an inlet.

Step 2: Gyratory Motion 

 The motor generates vibrations, which cause the sieve to vibrate in a gyratory motion. This motion spreads the material evenly across the screen surface.

Step 3: Particle Separation 

 As the material moves across the screen, particles smaller than the sieve openings pass through, while larger particles are retained on the screen surface.

Step 4: Discharge

 The separated particles are discharged through designated outlets, while the oversized particles continue to travel towards the outlet end of the sieve.

Applications of Rotary Vibrating Sieves

Rotary vibrating sieves find applications in a wide range of industries, including:

a) Food and Beverage Industry

 Rotary sieves are commonly used for sifting and classifying various food products, such as flour, sugar, spices, and powdered ingredients. They ensure product quality by removing impurities and oversized particles.

b) Pharmaceutical Industry

These round vibration sieves play a crucial role in pharmaceutical manufacturing processes, where the accurate separation of powders and granules is essential. They are commonly used in tablet production, powder coating, and active pharmaceutical ingredient (API) processing.

c) Chemical Industry

 Rotary vibrating sieves are widely used in the chemical industry for screening and separating different types of chemicals, pigments, dyes, and fertilizers.

5. Highly polished inner and outer surfaces of the barrel, no dead comer, easy to discharge materials, easy to clear, no cross-contamination. Confining the requirement of GMP.

7. The circular vibration sieve often connects with a drying machine, such as a vibration fluid bed dryer, fluid bed dryer, and so on.

8. The circular vibration sieve also connects to the powder grinding machine such 30B pin mill to make the big size materials into small pieces.

9. High efficiency, refined design, duration, and any powders and mucilage are suitable for use.

10. Easily replacing the screen, simple operation, and convenience washing.

11. Never jam the hole meshwork, no powder flying, filter size of the powder is between 500 mesh and 0.028 mm.

12. The highest layers of the vibrating screen machine are about 5 layers. But 3 layers are suggested.

Advantages of Using Rotary Vibrating Sieves

Using a rotary vibrating sifter machine offers several advantages over traditional screening methods. Here are some key benefits:

a) High Screening Efficiency

Rotary vibration sieves are designed to maximize screening efficiency. The gyratory motion and unique screen design ensure that every particle comes into contact with the screen surface, resulting in efficient and accurate separation.

b) Precise Particle Separation

 With adjustable screen openings and customizable sieve sizes, rotary vibrating sieves provide precise particle separation according to specific requirements. This level of precision is particularly important in industries where product quality and consistency are paramount.

c) Versatility and Adaptability

 Rotary vibrating sieves are versatile machines that can handle a wide range of materials, including powders, granules, and liquids. They can be easily customized with different screen types and mesh sizes to accommodate various applications.

d) Compact Design and Space-saving

Common Troubleshooting and Problem-Solving for Rotary Vibrating Sieves

Despite their reliability, rotary vibrating sieves may encounter occasional issues that can affect their performance. Here are some common troubleshooting tips:

a) Uneven Screen Motion

 If the screen motion is uneven or erratic, check for loose or worn-out drive belts, damaged motor bearings, or misaligned eccentric weights. Adjust or replace these components as necessary.

b) Screen Clogging

 If the screens are frequently clogged, consider using self-cleaning screen surfaces or implementing additional screening aids such as bouncing balls or ultrasonic systems to prevent blockages.

c) Insufficient Throughput

If the throughput is lower than expected, check for worn-out or damaged screens, incorrect screen mesh size, or improper screen tension. Replace or adjust the screens accordingly.

d) Excessive Vibrations or Noise

 Excessive vibrations or noise may indicate a mechanical issue, such as loose fasteners, unbalanced eccentric weights, or worn-out bearings. Inspect and repair or replace the affected components.

e) Inconsistent Particle Separation

 If the particle separation is inconsistent, ensure that the material feed is evenly distributed across the screen surface. Adjust the feed rate or implement feeders to improve distribution.
