Test Sieve

What is a Test Sieve?

A Test Sieve is a core tool for particle size analysis and classification of granular materials, consisting of two main parts: a sieve frame and a sieve mesh. The frame is typically made of stainless steel or aluminum alloy for strength and durability. The mesh, available in materials like woven wire or electroformed sheets, offers pore sizes ranging from microns to millimeters, adjustable for different screening needs. Through mechanical vibration or manual operation, it separates particles by size as materials move over the mesh. In laboratory testing and industrial classification, test sieves adhere to international standards (e.g., ISO 3310) and national standards (e.g., GB/T 6003), ensuring efficient screening and reliable support for material quality control and process optimization.

What are the Classifications of Test Sieves by Hole Shape?

 Test sieves are categorized by hole shape into round, square, woven mesh, and diamond holes, each tailored to specific particle characteristics. The hole shape directly affects screening efficiency and applicability, guiding targeted selection.
 
Round Hole Test Sieves: With circular apertures, they are suitable for screening regular-shaped particles (e.g., metal pellets). Their uniform force distribution reduces particle clogging, ensuring stable screening results.
 
Square Hole Test Sieves: Featuring square apertures, they are widely used in powder materials (e.g., cement, flour). The larger effective screening area improves efficiency, making them ideal for high-throughput scenarios.
 
Woven Mesh Test Sieves: Made by weaving metal wires, they have flexible aperture ranges (from microns to millimeters). They are cost-effective and versatile, applicable to both coarse and fine particle screening.
 
Diamond Hole Test Sieves: With diamond-shaped apertures, they adapt to irregular particles (e.g., mineral fragments). The inclined hole edges reduce particle adhesion, suitable for viscous or flaky materials.

What are the Types of Test Sieves?

Test sieves are divided into dry and wet types based on application scenarios, each with unique structural designs. Dry sieves suit free-flowing dry powders, while wet sieves handle viscous materials with liquids, meeting diverse screening requirements.

Type	Structural Features	Core Application Scenarios	Differential Advantages
Dry Test Sieve Frame	- Lightweight design (0.6mm wall thickness) - Single-layer silicone sealing ring - Standard pore size ≥45μm	Free-flowing dry powders such as cement, mineral powder, and flour	- Reduces vibration energy consumption - Prevents electrostatic adsorption of fine powders
Wet Wash Test Sieve Frame	- Thickened and reinforced frame (1.0mm wall thickness) - Double-layer waterproof silicone ring - Optional 316L anti-corrosion material - Pore size ≥20μm	Viscous materials containing liquids, such as clay, biological slurries, and mineral slurries	- Resists high-pressure water impact (0.3MPa) - Built-in flow guide grooves prevent mesh blockage
