working Principle

The vibratory sieving machine uses an upright motor as the excitation source. Eccentric weights are installed at the upper and lower ends of the motor, which cleverly converts the motor’s rotational motion into a composite motion in three dimensions: horizontal, vertical, and inclined. This composite motion is then transmitted to the screen surface, which drives the material to move in an outward-expanding involute trajectory on the screen surface. Therefore, it is also called a rotary vibrating screen.

The design of the vibratory sieving machine has many advantages. First, the material has a longer running trajectory on its screen surface, which helps to screen the material and improve the screening efficiency fully. Secondly, the utilization rate of the screen surface is high, which reduces the waste of materials during the screening process. In addition, by adjusting the phase angle of the weights at the upper and lower ends of the motor, the movement trajectory of the material on the screen surface can be flexibly adjusted to meet different screening needs.

Vibratory Sieving Machine Structures

vibrating screen separator

The gyro vibratory sieve separator is mainly composed of the following parts from top to bottom and from outside to inside:

  1. Dust cover, inlet.
  2. Screen frame, screen mesh, screen frame, clamp ring, outlet.
  3. Vibrating motor, vibration transmission body, upper and lower weights.
  4. Vibration isolation spring, spring washer.
  5. Base.


  1. It can screen particles, powders, and mucus within a specific range.
  2. The screening capacity can reach an amazing 600 mesh or 0.02 mm, while the filtration can capture particles as small as 5 microns.
  3. It can achieve one to five layers of graded screening and can perform two to six levels of classification or filtering at the same time.
  4. High efficiency, well-designed and sturdy, easy to replace the screen, simple operation and easy cleaning, ensuring continuous work.
  5. The direction of the discharge port can be adjusted 360 degrees, and the rotating vibrating screen automatically discharges impurities and coarse materials.
  6. The mesh has a unique design to extend the life of the screen, and it only takes 3-5 minutes to replace the screen.
  7. The small size can match the production line operation with limited space and is easy to move.
  8. The closed structure meets environmental protection requirements.

Custom Vibratory Sieving Machine

The vibratory sieve allows a throughput of 100 to 5000 kg/hour, depending on the product, mesh size, and feed flow of the machine. It is suitable for screening from 36 microns to 25 mm. It allows the use of 5-layer sieves, which can separate up to 6 products of different specifications and sizes. It is widely used in food, medicine, chemical industry, metallurgy, abrasives, ceramics, and coatings.


The model of the round vibratory sieve machine is mainly reflected in the difference in the screen area and the processing capacity of the screen machine. The larger the screen model, the larger the screen area, and the greater the output of the screened material.

Material selection for Vibratory Sieving Machine

Vibratory sieving machines are usually made of four materials: all stainless steel, semi-stainless steel for contact materials, carbon steel, and plastic materials.

1. All stainless steel material

Food and medical-related industries usually use 304 stainless steel for the sanitary vibratory sieve. Stainless steel has better hardness, plate thickness, and wear resistance. It is also strictly polished and polished, making it easier to clean without affecting the quality of the finished product.

2. Semi stainless steel material

The part in contact with the material is made of stainless steel, and the base is made of carbon steel. It is suitable for material screening in the food, pharmaceutical, and chemical industries. Lower price than all stainless steel.

3. Carbon steel material

Carbon steel material does not have high material requirements and is suitable for screening some construction and metallurgical powder particles. The price is much cheaper than other materials.

4. Plastic material

The part in contact with the material is made of polypropylene (PP plastic), which is a screening solution for materials that are corrosive to metals such as carbon steel and stainless steel.

specially customized

In addition to the standard model of the vibratory sieve machine, the vibratory sieve can also be specially customized (non-standard) according to different material screening requirements:
