A High Frequency Screen is a type of vibrating screen designed for efficient particle separation, primarily used in mineral processing, production globale, et industries du recyclage. It operates at a higher frequency (typically 3,600–7,200 RPM) compared to conventional screens, enabling better separation of fine materials.

Principales fonctionnalités:
1. High Vibration Frequency:
- Uses rapid vibrations to reduce material blinding (clogging) and improve screening efficiency for fine particles (down to 45 microns or less).

2. Smaller Mesh Sizes:
- Ideal for separating fine materials like sand, charbon, minerai de fer, or crushed aggregates.

3. Low Amplitude:
- High-frequency oscillations with small stroke lengths prevent excessive wear and energy consumption.

4. Conception modulaire:
- Often includes replaceable screen panels (polyurethane or stainless steel) for easy maintenance.

5. Applications:
- Traitement des minéraux (par ex., dewatering, classification).
- Aggregate screening (sable, gravier).
- Recyclage (waste sorting, metal recovery).
- Chemical and food industries (powder separation).

Avantages:
- Higher throughput for fine materials.
- Reduced moisture content in dewatering applications.
- Less clogging due to intense vibration.

Inconvénients:
- Higher initial cost than traditional screens.
- More maintenance due to intense vibration wear on components.

Fabricants:
Popular brands include Derrick Corporation, Outotec, Schenck Process, and SWECO.
