The test sieve is a laboratory equipment used for particle size analysis. Its core components usually include a stainless steel frame and woven cloth (also called a sieve). The materials and characteristics of these two are crucial to the performance of the test sieve.

The role and characteristics of stainless steel frames and woven cloth in test sieves

①The role and characteristics of stainless steel frames

Stainless steel frame provides solid support, prevents deformation and damage, is corrosion-resistant, easy to clean and has uniform standards in the test sieve.

Stainless steel frame is the carrier of the sieve, which has sufficient strength and rigidity to protect the sieve from being stretched or damaged under long-term and high-intensity use, ensuring the accuracy of the screening results.

The excellent corrosion resistance of stainless steel can ensure that the frame can be used for a long time in various environments without rusting or being corroded, avoiding contamination of samples. The surface is smooth, not easy to adhere to materials, easy to clean, and helps to keep the sample pure and avoid cross contamination.

The frame size of the test sieve usually needs to meet international or industry standards so that the sieves produced by different manufacturers can be used universally to ensure the comparability of test results. Stainless steel is easy to process with precision and can meet these standard requirements.

②The role and characteristics of woven cloth (screen)

Woven cloth can achieve accurate particle size separation in the test sieve, and the material is diverse. The weaving method, wear resistance and precision are also very important.

The accuracy of the mesh size of the woven cloth directly determines the accuracy of the particle size analysis. Through woven cloths of different mesh sizes, particles of different size ranges can be separated.

The material is usually stainless steel (such as 304, 316, etc.), and the weaving method (such as plain weave, twill weave, etc.) and the wire diameter will affect the strength of the screen, the uniformity of the aperture and the possibility of clogging.

During the screening process, the material and the screen will rub, so the woven cloth needs to have a certain wear resistance

The mesh number and aperture size of the test sieve also need to meet the relevant industry standards.

Analysis of the materials and characteristics of stainless steel frames and woven cloth

Stainless steel frame

Common models: 304 stainless steel (food/chemical grade), some high requirements use 316 stainless steel

Features: high strength, not easy to deform; corrosion resistance, oxidation resistance; washable and reusable; suitable for wet or dry screening.

Woven cloth/screen material:

Type	Features	Application
Stainless steel woven mesh	High weaving density, strong mechanical strength, suitable for micron-level fine screening	powder particle size analysis, cement, mineral powder, etc.
Nylon woven cloth	Good flexibility, acid and alkali resistance, suitable for liquid samples (such as soy milk, chemical liquid)	food filtration, laboratory sample filtration, etc.
Polyester/polyester cloth	Strong wear resistance, low price, suitable for conventional fine screening	pharmaceuticals, pigments, resins, powders, etc.

Technical parameters of stainless steel frame and woven cloth (common specifications)

Item	Parameter range
Screen diameter	Common: Φ200mm, Φ300mm, Φ400mm, Φ450mm
Screen mesh number (mesh)	5 mesh ~ 500 mesh (even up to 635 mesh)
Screen hole accuracy	±1~5 μm (depending on weaving accuracy)
Screen frame height	Usually 50mm or 75mm (customizable)
Frame thickness	≥0.5mm, generally the thicker the better

Suggestions for selecting stainless steel frames and woven cloth

Frame material selection: If corrosion resistance/food use is required, select 304/316 stainless steel

Screen material selection:

Metal stainless steel mesh is recommended for dry powder/powder

Nylon or polyester cloth is recommended for liquid/soy milk

Mesh selection: Select according to the sample particle size, the larger the mesh, the finer (such as 100 mesh = about 150μm)
