In mineral processing, coal washing, and aggregate classification industries, the efficient and precise screening of wet fine materials (especially below 0.5mm) presents significant technical challenges. Traditional screening equipment often suffers from blinding, low efficiency, and rapid wear.

The innovative High-Frequency Multi-Layer Vibrating Fine Screen emerges as a superior solution, leveraging independently developed core technologies and refined engineering to overcome wet fine-particle screening challenges.

I. Ingenious Craftsmanship: Unmatched Reliability and Durability

The core advantages first lie in exceptional structural reliability and extended service life, achieved through two critical manufacturing techniques:

1. Rivet-Connected Main Structure:

• Eliminates risks of stress concentration, deformation, and potential cracks inherent in traditional welding.
• High-strength rivet connections ensure superior structural rigidity and holistic stabilityduring long-term high-frequency vibration.
• Key Advantage:Drastically reduces fatigue damage risk from vibration, minimizing unplanned maintenance downtime and labor intensity, ensuring continuous production stability.

2. Full Polyurea Coating Protection:

Entire screen surface (especially critical material-contact areas) treated with advanced polyurea elastomer spray technology.

Key Advantages:

• Exceptional Wear Resistance:High abrasion resistance coefficient protects against material scouring, ideal for abrasive minerals or coal slimes.
• Superior Corrosion Resistance:Forms a continuous, dense barrier against moisture and corrosive agents, ideal for wet screening environments, effectively preventing rust.
• Extended Lifespan:Dual protection (structural + surface) significantly extends core equipment life, reducing total cost of ownership.

II. Core Technology: Independently Developed Polyurethane Fine Screen Mesh – Overcoming Blinding

The biggest hurdle in wet fine-particle screening is “blinding.” The core breakthrough lies in its independently developed proprietary polyurethane fine screen mesh:

Special Material & Structure: High-performance polyurethane with unique formulation and molding ensures excellent elasticity, toughness, and wear resistance. Scientifically designed apertures with smooth walls.

Core Advantages:

• Outstanding Anti-Blinding Performance:Polyurethane elasticity enables micro-deformation during high-frequency vibration, generating an effective “self-cleaning effect,” drastically reducing slime adhesion and aperture blockage, ensuring sustained high throughput.
• High Throughput:Anti-blinding properties enable processing of larger volumes of wet fine material per unit time.
• High Screening Efficiency:Excellent aperture openness reduces fine particle passage resistance, enhancing classification accuracy and screening efficiency, especially for ultra-fine particles.
• Extended Mesh Life:Superior wear and fatigue resistance prolongs mesh replacement intervals.

III. High-Frequency Multi-Layer Design: Multiplied Efficiency

Building on and optimizing the classic multi-layer screen advantages:

1. High-Frequency Vibration:Driven by high-efficiency vibratory motors, producing high-frequency, low-amplitude vibration. Ideal for promoting dispersion and passage of fine, wet, sticky materialson the deck, boosting capacity and accuracy.
2. Multi-Layer Stacking:Vertically stacked screen frames (typically 2-5 layers), each equipped with polyurethane mesh of different apertures.
   3. Key Advantages:
   • Multi-Grading in One Pass:Feed material once, simultaneously yield multiple qualified products of different sizes, simplifying processes and multiplying efficiency.
   • Space-Saving Design:Multi-layer stacking offers far greater processing capacity per unit footprint than single-layer screens.
   • Precise Classification:High-frequency vibration combined with anti-blinding mesh ensures high-precision, high-efficiencyclassification of fine particles.

   IV. Broad Application Scope

   It excels in critical wet fine-particle classification applications:

   1. Coal Industry:
   • Efficient Coarse Slime Separation:Precisely separates qualified clean coal from high-ash impurities in coarse slimes.
   • Deep Pyrite Removal from Fine Coal:Effectively removes fine pyrite (FeS₂) particles from fine coal.
   2. Mineral Processing:
   • Fine Mineral Separation:Size classification and recovery of fine-grained minerals (Sn, Pb, Zn, Ti, W, etc.).
   • Precise Ore Sand Grading:Size control for various ore sands (e.g., quartz sand, feldspar sand).
   3. Aggregates & Building Materials:
   • Fine Classification of Manufactured Sand:Controls gradation modulus and rock powder content in finished sand.
   • Impurity Removal from Sand:Efficiently removes high-density minerals (e.g., iron fragments, garnet) or low-density impurities (e.g., lignite, peat, wood chips) from sand.
   4. Environmental & Resource Recovery:Fine particle separation in solid waste treatment, recycled aggregate classification.
