As the core sorting equipment in the industrial field, mining screens are used throughout the entire process from raw material processing, production and processing to waste recycling Through precise screening , efficiency improvement and resource optimization , they have become an indispensable "technological link " in the modern industrial system
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).
选择取决于物料硬度、含水量、颗粒大小和冲击力：
潮湿或粘性物料 → 聚氨酯筛网（防堵塞）
高磨损物料 → 锰钢编织网或冲孔板
高精度筛分 → 不锈钢编织网
重冲击物料 → 钢边聚氨酯板或橡胶筛板
选择正确的筛网可以提高产量并减少停机时间。
使用寿命随物料磨蚀性、振动频率、安装张力和筛网类型而变化：
聚氨酯筛网：3-12 个月
锰钢筛网：1-6 个月
不锈钢筛网：2-8 个月
橡胶板：4-12 个月
正确的张紧和选择合适的孔径可显著延长使用寿命。
堵塞由于水分、不规则颗粒形状或不合适的孔径设计引起。 预防方法：
使用自清理筛网（波浪型或琴弦型）
更换为聚氨酯防堵塞筛网
调整振动振幅和筛面倾角
对潮湿或泥泞物料进行预筛分
防堵塞解决方案大大提高了筛分效率。
更换期间的关键点包括：
确保整个筛网的张力一致
检查筛框是否有变形
钩子类型或紧固系统与您的筛机匹配
清理筛床以清除残留物料
正确的安装可减少破损并提高筛分精度。
筛分效率可以通过以下方式提高：
选择合适的孔径和筛网材料
调整振动频率和筛子倾角
保持均匀的物料进给
使用多级筛分设计
定期维护筛床和筛网
通常可实现 10-30% 的效率提升。
