Round vibrating screen also called a circular vibrating screen, with a circular appearance, is a kind of high-precision fine powder screening equipment, which can be used for screening and filtering granules, powder, mucus, and other materials. It is widely used in food, medicine, chemical, metallurgical powder, paint, ceramic slurry, and other industries.

Round vibrating screens in the material can be divided into the following three types: stainless steel vibrating screen, carbon steel vibrating screen, and corrosion Plastic PP vibrating screen.

1. Standard Round Vibrating Screen

Standard round vibrating screen, the screen body frame is made of stainless steel, and the base is made of carbon steel. The stainless steel frame provides corrosion resistance and high strength, while the carbon steel base provides stable support.

This design can handle various types of materials and environments. Mainly used for screening particles, powders, etc. The smallest sieving is 500 mesh or 0.028mm, and the smallest filtration is 5 microns.

Grading and screening, it can screen one to five layers of mesh, and can perform two to six levels of sorting or filtration at the same time, with a grading accuracy of over 98%.

2. Full Stainless Steel Vibrating Screen

Stainless steel vibrating screens are commonly used for screening and filtering powders, granules, liquids, and other materials.

They are commonly used in food processing, chemical, pharmaceutical, and other industries. Stainless steel vibrating screens are rugged and easy to clean and maintain for food-grade and pharmaceutical-grade applications.

3. Carbon Steel Vibrating Screen

Carbon steel rotary vibrating screens offer durability and corrosion resistance and are commonly used in demanding industrial applications such as pharmaceutical, food processing, and chemical processing.

4. Anti Corrosion Plastic PP Polypropylene Vibrating Screen

The Anti Corrosion Plastic PP Polypropylene Vibrating Screen completely adopts non-metallic materials from the screen frame, screen, and cleaning device, which eliminates the problem that some special materials will produce chemical reactions in contact with metal. It’s the current effective solution to the oxidation, corrosion of steel material screening, impurity removal, and filtering program, and ensures that the material in the screening process will not deteriorate.

Working Principle

The working principle of round vibrating screen is made of the vertical motor as the excitation source, and there are eccentric hammers installed at the upper and lower ends of the motor, which transforms the rotary motion of the motor into three-dimensional horizontal, vertical, and inclined motion, and then transmits this motion to the screen surface.

Adjusting the phase angle of the upper and lower ends can change the trajectory of the material on the screen surface, because its vibration principle of operation is also known as the “three-dimensional vibration screening filter”.

  1. Wide application: essence and mucus can be sieved, 1-5 layers of screen mesh filtration, sieving range is 5~500 mesh.
  2. Unique mesh frame design, easy to change the mesh (only 3-5 minutes), simple operation, easy to clean.
  3. Fully sealed structure can ensure that the mesh is not blocked and the powder does not fly.
  4. Discharge port can be adjusted 360 arbitrarily, impurities, coarse material automatically discharged, 24 hours continuous operation.
  5. Portable design, small size, space-saving, easy to move.
  6. It can be designed according to the user’s demand, such as adding edge type, gate type, powerful type, sealed type, etc.

Application of Round Vibrating Screen

  • Chemical industry: resin, paint, pigment, rubber, carbon black, activated carbon, co-solvent, glue powder, yuanming powder, polyethylene powder, quartz sand, and so on.
  • Medicine: Chinese medicine powder, western medicine powder, medicine raw material powder, etc.

Round Vibrating Screen Manufacturer

Sanyuantang Machine is a professional manufacturer and factory of round vibrating screens in China. we have excellence in manufacturing technology and innovative manufacturing concepts, the company has increased and become one of the production bases of vibration machinery in China.


1. Must be uniform feeding: the feeding amount to meet the equipment processing capacity shall prevail. Too much material at one time, hindering the normal movement of the material on the screen surface, not only easily makes the screen mesh fatigue loose, but also will greatly reduce the material handling capacity. Giving a large amount of material at one time will result in the unbalanced operation of the motor load suddenly increased, resulting in motor damage, and reducing motor life. If the amount of material reaches the handling capacity of the equipment, that is, a waste of energy, but also reduces the output.

2 must be installed buffer hopper, the material directly impacts the mesh surface, not only consuming the vibration source produced by the excitation force but more likely to cause mesh damage and screen fatigue, which affects the yield and screening and filtering output.

Comprehensive analysis The production efficiency of using a vibrating screen maybe 5-10 times higher than that of manual screening, and the product accuracy will also increase by more than 95%. This is the difference between traditional manual screening and Sanyuantang vibrating screen operation. An electric screening machine (vibrating screen) effectively improves product quality and saves production costs.

We have many casesSolid-liquid mixing. Take soybean milk as an example, there are often granular solid beans in it, and the rotary vibrating sieve can achieve solid-liquid separation very well, achieving a satisfactory effect for the enterprise. Sieve out impurities. If there are large particles in the powdery material, the rotary vibrating sieve can quickly sieve them. Size grading. We have dealt with grain, quartz sand, insects, etc., and we divide the rotary vibrating screen into one layer, two layers, three layers, etc. The more layers, the more grades of materials screened out, and the finer they are. Thick and fine materials can be separated, and large and small materials can be separated.
