1. Raw material pretreatment and grading

( 1 ) Metal smelting:

In the metallurgical industries such as iron ore and copper ore, ore screens are used to classify the particle size of crushed ore (such as 0-10mm charging material and 10-30mm return material) to ensure the air permeability and smelting efficiency of blast furnaces or electric furnaces.

effect:

Improve metal recovery rate (e.g. iron ore grade increased by 5%-8% after screening);

Reduce coke consumption (uniform particle size reduces "bridging" phenomenon in the furnace).

( 2 ) Chemical raw material processing:

Screening of catalyst carriers (such as alumina balls), plastic particles, and fertilizer raw materials to control particle size distribution (such as urea particles 1-4mm) to ensure uniformity of chemical reactions.

effect:

Avoid pipe blockage caused by agglomeration;

Improve catalyst activity (such as molecular sieve particle size error ≤ 0.05mm).

2. Precision production in manufacturing

( 1 ) Powder metallurgy:

Screening of metal powders (such as titanium powder and tungsten powder) to a specific particle size (such as below 200 mesh) for precision manufacturing such as 3D printing and MIM (metal injection molding).

effect:

Ensure consistency of product density and mechanical properties;

Reduce sintering deformation (coarse particle ratio ≤ 0.1%).

( 2 ) Electronic materials:

Sorting silicon micropowder (raw materials for photovoltaic cells), ceramic dielectrics (MLCC capacitors), etc., with precision reaching nanometer level (such as 325 mesh sieve filtering 5μm particles).

effect:

Improve the yield rate of electronic components (e.g., the defect rate of MLCC capacitors is reduced by 30% after screening);

Meet the ultra-high purity requirements of semiconductor materials (impurity content ≤ 1ppm).

3. Environmental protection and resource recycling

( 1 ) Industrial solid waste treatment:

Sorting industrial wastes such as fly ash, steel slag, and red mud to extract recyclable components (such as iron particles in steel slag and floating beads in fly ash).

effect:

The resource utilization rate increased to over 60%;

Reduce landfill costs (reduced by US$50-100 per ton of solid waste disposal fees).

( 2 ) Wastewater treatment:

Use stainless steel mesh (pore size 0.1-1mm) to intercept suspended solids in industrial wastewater (such as textile printing and dyeing fibers, electroplating sludge).

effect:

Protective membrane treatment system, extending the life of reverse osmosis membrane by 2-3 times;

Comply with industrial wastewater discharge standards (such as SS≤30mg/L).

4. Food and pharmaceutical industries

( 1 ) Food processing:

Sifting flour, powdered sugar, milk powder, etc. to remove lumps or foreign matter (such as metal shavings) in compliance with HACCP food safety standards.

effect:

Ensure product fineness (such as flour passing through a 100-mesh sieve);

Prevent consumer complaints and recall risks caused by foreign matter.

( 2 ) Pharmaceutical industry:

Use 316L stainless steel vibrating screen to grade drug powders and granules (e.g. 20-60 mesh) to meet GMP clean room requirements.

effect:

Controlling drug dissolution rate (particle size affects bioavailability);

Avoid cross contamination (fully enclosed screening design).
