Introduction of Lab Vibrating Screen

Introduction of Lab Vibrating Screen

Lab vibrating screen can quickly and efficiently measure solid particle sizes from 125 mm to 20 μm. Special sieves with pore sizes smaller than 20 μm can be used, but it should be understood that the finer the sieve, the more likely certain types of particulate solids will clog or clog the pore size. However, "micro" sieving down to 5 μm is possible using special techniques.

layers of lab vibrating screen

Lab vibrating screens are available in 75mm, 100mm, 200mm, 300mm, and 400mm, among which standard screens between 200mm and 300mm are more common. In addition, stainless steel, nylon, and all-copper screen frames can be selected according to requirements. The sieve machine can be placed up to 8 layers of test sieves (including the bottom sieve), which can accurately separate 2 to 7 particle segments of a particle at the same time, and can be automatically shut down at regular intervals; ensuring the repeatability of the experiment.

Types of Lab Vibrating Screen

  • Laboratory Test Sieves

    Laboratory Test Sieves

    It is divided into 300 type and 400 type, mainly to install screen frames with different diameters, and the mesh of the matching screen frames can generally reach 8 mesh to 400 mesh. Used in various laboratories for the separation and classification of powders, granules, and suspensions.


  • Ultrasonic Lab Vibrating Screen

    Ultrasonic Lab Vibrating Screen

    Equipped with an ultrasonic transducer, it is a laboratory vibrating sieve machine for fine powders with high static electricity, strong adsorption, high density, and light specific gravity. It sieves as fine as 20 microns without clogging the screen.


  • Electric Sieve Shaker

    Electric Sieve Shaker

    The electromagnetic vibrator is used as the vibration source, and the vibration frequency reaches 3000 times/min, which improves the screening efficiency of fine materials, and the dry screen can screen to 20um (635 mesh)..


  • Rotap Sieve Shaker

    Rotap Sieve Shaker

    It has dual movements of slapping and reciprocating, and can control the screening time at regular intervals. It is suitable for high-intensity and high-frequency repeated use in the production and grading process of diamond micropowder and superhard material industries.

Application of Lab Vibrating Screen


Lab vibrating screen is mainly used in the laboratory to classify and determine the particle size of powders, bulk particles and suspensions. The samples of different sizes are separated through sieves of different sizes, which can quickly and effectively measure the size of solid particles from 125 mm to 20 μm. Stackable 8-layer screen frame (including screen bottom).

Benefits of Lab Vibrating Screen

Mesh sizes from 20 µm to 125 mm

In the inspection process, the screening accuracy is accurate and the screening efficiency is high, which can quickly and effectively measure the size of solid particles from 125 mm to 20 μm.

SUS304 stainless steel

The test screen case and vibration plate are made of high-quality SUS304 stainless steel, which is resistant to corrosion, high temperature, not easy to rust, and non-magnetic.

Automatic timer shutdown

Different working hours can be realized through time relay, which can be set from 0 to 99 minutes to reduce inspection errors, ensure the consistency of sample analysis data, and make standard judgments on product quality.

Install the multi-layer test sieve

8 test sieves (including sieve bottoms) can be installed, and a product can be accurately separated into 2-7 particle segments at the same time.

Structure of Lab Vibrating Screen

Screen Material

Screen: The screen is the most technical part of the lab vibrating screen. The most commonly used mesh type is stainless steel woven wire mesh. Opening sizes are 5 inches (125 mm) to 635 mesh (20 microns).

Screen Frame: Frames are circular metal rings that hold the mesh in place. Standard frame sizes in the U.S. are 3 inches, 8 inches, and 12 inches. Internationally, 100mm, 200mm and 300mm are standard sizes. The screen frame can be made of stainless steel or brass.

Skirt: The main function of the skirt is to allow the sieves to be stacked without tipping over.

Steps To Use Lab Vibrating Screen

1. The equipment should be placed horizontally, confirm that the power supply and the nameplate requirements are in line with the requirements, and ensure that the grounding; pay attention to the vibration part can not be in contact with other objects; check whether the bolts of each part are locked.

2. Determine the standard screen frame to be selected according to the tested materials and the corresponding standards.

3. Stack the screen frames on the vibrating plate of the lab vibrating screen from the bottom to the top according to the aperture from small to large.

4. Put the material to be tested into the standard screen frame at the upper end, cover the upper cover of the standard screen, adjust the height of the adjusting rod according to the total height of the standard screen frame, and then use the pressure plate and the lock nut to position and press the standard screen frame ( Note: The force on both sides should be the same).

5. Set the running time on the timer according to the nature of the material and the feeding amount, then turn on the power switch, and the standard sieve will start to work.

6. After the work stops, unscrew the lock nut, remove the pressing plate, and carefully remove the standard screen frame.

7. Cut off the power.
