Ekran me frekuencë të lartë
A High Frequency Screen is a type of vibrating screen designed for efficient particle separation, primarily used in mineral processing, prodhimi agregat, dhe industritë e riciklimit. It operates at a higher frequency (typically 3,600–7,200 RPM) compared to conventional screens, enabling better separation of fine materials.
Karakteristikat kryesore:
1. Frekuenca e lartë e dridhjeve:
- 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, qymyr, mineral hekuri, or crushed aggregates.
3. Amplitudë e ulët:
- High-frequency oscillations with small stroke lengths prevent excessive wear and energy consumption.
4. Dizajn modular:
- Often includes replaceable screen panels (polyurethane or stainless steel) for easy maintenance.
5. Aplikacionet:
- Përpunimi i mineraleve (p.sh., dewatering, klasifikimi).
- Aggregate screening (rërë, zhavorr).
- Riciklimi (waste sorting, metal recovery).
- Chemical and food industries (powder separation).
Avantazhet:
- Higher throughput for fine materials.
- Reduced moisture content in dewatering applications.
- Less clogging due to intense vibration.
Disavantazhet:
- Higher initial cost than traditional screens.
- More maintenance due to intense vibration wear on components.
Prodhuesit:
Popular brands include Derrick Corporation, Outotec, Procesi Schenck, and SWECO.
