What are laboratory woven wire mesh sieves?

Laboratory woven wire mesh sievesuse the physical barrier effect of their mesh openings to separate mixed materials according to particle size differences, while removing impurities and obtaining particle size distribution data. The equipment can perform dry or wet sieving of fine powders, dry granules, brittle and hard powders, as well as moist and sticky materials.

Mesh sizes can range from 20 micrometers to 5 millimeters, with common specifications including 20 μm, 45 μm, 75 μm, 150 μm, 300 μm, 600 μm, 1 mm, 2 mm, and 5 mm, ensuring that particles do not pass through or clog the sieve during the sieving process. Sieving can separate excessively coarse or fine materials to obtain materials with uniform particle size.

Characteristics of Laboratory Woven Wire Mesh Sieves

The characteristics of laboratory woven wire mesh sieves determine their performance and application range. Firstly, regarding materials, stainless steel (such as 304 or 316) is most commonly used to ensure durability, corrosion resistance, and chemical compatibility with materials, making it particularly suitable for most general applications and those requiring rust prevention. For certain industries (such as grain processing), brass is sometimes chosen to avoid sparks or specific chemical reactions. When handling materials sensitive to metals, non-metallic screens such as nylon or polyester are used.

The mesh size and screen structure are its most crucial parameters. Mesh size strictly adheres to international standards, typically measured in micrometers or millimeters, corresponding to standard mesh counts. The screen consists of a uniform mesh of metal wires interwoven in a plain or twill pattern. Precise control of wire diameter and mesh size ensures the screen is both robust and durable, enabling high-precision particle grading and sieving.

Common diameters for laboratory woven wire mesh sieves include 3in (75mm), 4in (100mm), 6in (150mm), 8in (200mm), and 12in (300mm), selected according to laboratory standards and the size of the vibrating sieve. The frame material is generally stainless steel or nickel-plated steel, but aluminum alloy or other metal frames are also available to ensure the sieve is stable, corrosion-resistant, and easy to clean. The sieve aperture ranges from 20μm to 25mm, offering high precision and conforming to standards such as ASTM E11 and ISO 3310-1, accurately classifying particle sizes and ensuring reliable experimental data.

Laboratory Woven Wire Mesh Sieves Application Scenarios

Laboratory woven wire mesh sieves are suitable for most scenarios requiring sieving. For example, fine sieving of traditional Chinese medicine powders involves classifying them using sieves of different aperture sizes to remove lumps or ultrafine powders. The classified particles can be used for tableting, capsule filling, or further experimental analysis. Spice particles are poured into sieves and sieved by vibration or manually; large particles and impurities remain on top, while small particles are collected through the sieve openings. These particles can be used for quality control before production or experimental formulation research. Coal powder is placed in a sieve and classified by vibrating sieves or manual tapping. The weight percentage of particles of different sizes is determined for particle size analysis and process optimization.
