Experimental Sieve

What is Experimental Sieve?

Experimental Sieve is a sieving test instrument used in the laboratory, usually used for sieving powder, granules and other materials, and consists of two parts: a sieve frame and a sieve body. The size of the material is controlled and screened by the screen hole size of the screen frame, and its main screening power comes from the vibrating screen of the screen body.

Testing pharmaceutical powders: very fine powder No. 8 sieve (150 mesh) No. 9 sieve (200 mesh) no less than 95% of the powder.

It is a screening equipment used in laboratories or scientific research fields for screening, classifying or filtering solid particles or powders. Experimental sieves are usually used for experimental purposes such as particle analysis, particle size measurement, particle distribution analysis, etc.

Experimental Sieve Application

Experimental Sieve is mainly used for the analysis and testing of the particle size of materials, and can be used to measure the size range and distribution of particles, as well as particle shape, density and other characteristics. Its application scope covers many fields such as chemical industry, mining, food, medicine, metallurgy, etc. The specific materials include aggregate, soil, cement, graphite powder, grain, sand, glass powder, etc.

Experimental sieves are often used in scientific research laboratories for particle analysis, particle size measurement, particle distribution analysis and other experimental research work. Experimental sieves are often used in the mining and metallurgical fields to screen and analyze ore particles to help improve the efficiency of ore beneficiation. In the chemical industry, experimental sieves are used for screening and classifying chemical product particles to ensure product quality and production efficiency.

How does the experimental sieve work?

Spread the sample to be tested evenly on the experimental sieve, and make the particles in the sample pass through the sieve through vibration or sieving. Particles of different sizes will remain on the screens of different apertures or at the bottom of the screen box, thereby achieving particle size classification.

Advantages of experimental sieves

1.Prevent material clogging: through high-frequency vibration, the electrostatic interaction and surface tension between materials are destroyed. You can also choose appropriate screen materials, such as stainless steel, nylon, etc., to improve the wear resistance and corrosion resistance of the screen and reduce clogging phenomenon.

2.Conduct particle size analysis: Screens with different apertures can accurately classify materials according to particle size, obtain particle size distribution data, and provide a basis for subsequent experiments. The screening results have good repeatability, ensuring the reliability of the experimental data.

3.Reduce sample loss: The experimental sieve has a compact structural design. By stacking multiple layers of sieves, sample loss can be reduced, the recovery rate can be improved, and sample splashing and loss during the screening process can be effectively prevented.

4.Improve screening efficiency: Use efficient vibration methods, such as vibration motors, ultrasonic vibration, etc., and adjust the inclination angle of the screen to speed up the movement of materials and improve screening efficiency.

How to clean up Experimental Sieve

1. Turn off the power of the test sieve

2. Loosen the iron buckles on the four corners to fix the standard sieve, remove the upper cover of the vibrating screen, and remove the two layers of screens.

3. Clean up the rest of the standard inspection sieve with a vacuum suction hose and a rag.

4. Use compressed air to clean the particles and powder from the sieve. If the particles and powder are stuck in the sieve and cannot come out, you can use a screwdriver to push out or tap the sieve.

5. Install the upper small hole screen - large hole screen - upper cover in order

6. The tools used when cleaning up the standard inspection sieve must be cleaned.
