Sieve Mesh

What is a sieve mesh?

Sieve mesh is a mesh tool used to separate particles or powders by particle size, usually woven or stamped from wire, nylon, polyurethane or other materials. The core function of a sieve is to classify materials by particle size through its aperture size, and is widely used in industry, agriculture, food, medicine, construction and other fields.

Classification of sieves

1. Classification by weaving method

Plain weave: tightly woven, uniform aperture, high strength, suitable for fine screening, such as medicine and chemical industry

Twill weave: higher strength, can screen finer particles, suitable for high-demand screening

Hook and loop mesh: larger aperture, suitable for coarse particles, suitable for mining and construction

Grinded mesh: cross-woven, stable structure, suitable for high-strength screening

2. Classification by material

Type	Picture	Structural features	Applicable scenarios	Advantages	Limitations
Woven screen		Wire/synthetic fiber warp and weft weaving	Medium and fine particles (0.045~20mm)	High porosity (35%~75%)	Easy to deform, short life
Punching screen		Metal plate stamping	Large particles (5~100mm)	High strength, wear resistance	Low porosity (≤50%)
Polyurethane screen		PU elastomer molding	Wet materials or high wear scenarios	Anti-blocking net, corrosion resistance	High price (2~3 times that of metal mesh)
Electroforming screen		Electrolytic process precision molding	Ultra-high precision screening (5~500μm)	Aperture tolerance ±1μm	Only for small areas (extremely high cost)
Sintered screen		Metal powder sintering	High temperature/high pressure environment (such as petroleum screening)	Resistant to 800℃ high temperature, multi-layer filtration	Heavy weight, not easy to replace

What can a sieve be used for?

The main function of a sieve is to classify particles into different grades or size ranges based on their size. The structure of a sieve is usually made up of parallel filaments (wires or synthetic fibers) interwoven to form a series of holes or meshes. The size of these holes can be adjusted as needed to meet the screening requirements of different particle sizes.

Features of sieve mesh

Aperture size: The aperture of the screen determines the size of the particles that can pass through, usually expressed in mesh (number of holes per inch) or millimeters (mm).

Various materials: Depending on the application, screens can be made of stainless steel, high carbon steel, nylon, polyurethane and other materials.

Weaving method: The screen can be a woven mesh (woven from wire or fiber) or a punched plate (made by stamping process).

Wear and corrosion resistance: High-quality screens are wear-resistant, corrosion-resistant, and tensile-resistant, suitable for long-term use.

How does the sieve mesh work

Material conveying: The material to be screened is evenly conveyed to the screen surface.

Vibration or rotation: The screen moves by vibration or rotation, causing the material to move relative to the screen surface.

Particle separation: Particles larger than the sieve holes are retained on the screen surface, while particles smaller than the sieve holes fall through the sieve holes to achieve particle size separation.

Nylon screen	nylon fiber	good flexibility, wear resistance, often used in food and medicine industries	food, medicine, electronics and other industries

Advantages of the sieve mesh

Precise screening effect: The aperture of the sieve can be precisely adjusted as needed, which can achieve accurate screening and grading of particles and help analyze the size distribution of particles.

Efficient screening process: The sieve structure is reasonably designed, and particles can pass through the sieve quickly during the screening process, improving screening efficiency and saving time and labor costs.

Strong durability: High-quality sieves are usually made of durable materials, have high wear resistance and corrosion resistance, and can be used stably for a long time.

Diverse choices: The sieve can choose meshes of different apertures according to different particle sizes and screening requirements to meet different screening needs.

Application of sieve mesh

Sieve Meshes are widely used in mining, construction, agriculture, food processing, chemical industry, environmental protection, medicine, textile, electronics, energy, water treatment and automobile manufacturing, mainly for separation, filtration and classification.
