Magnetik Ayrıştırıcı Malzeme Geri Kazanımı İçin
A magnetic separator removes ferrous metal from plastic flakes, mixed waste, mining material, and other bulk streams before the metal damages crushers, granulators, extruders, or final sorting equipment.
- Captures tramp iron, steel pieces, screws, nails, wire, and other magnetic contamination from moving material streams.
- Protects downstream equipment while improving the purity and resale value of recovered material.
- Available as overband magnets, drum magnets, magnetic pulleys, and line-specific separation modules.
How a Magnetic Separator Works
A magnetic separator places a controlled magnetic field near the material flow. Ferrous metal responds to the magnetic force and separates from plastic, paper, glass, wood, minerals, or other non-magnetic material.
1. Material Feed
Material moves across a conveyor, chute, drum surface, or pulley. A consistent layer improves separation because the magnet can reach each particle more evenly.
2. Magnetic Capture
Iron and steel are attracted by the magnetic field while non-magnetic material continues along its normal path.
3. Separate Discharge
Captured metal is discharged into a separate collection point, reducing contamination and protecting downstream machines.
Manyetik Ayırıcı Çeşitleri
The right magnetic separator depends on where the metal appears, how deep the material layer is, and whether you need manual or continuous discharge.
Endüstriyel Manyetik
Installed above a conveyor belt.
Suitable for removing large ferrous contaminants from plastics, waste streams, wood, and aggregate before crushing or sorting.
Drum Magnet
Magnetic drum with continuous discharge.
Useful when material passes directly over the drum and the line needs automatic separation of ferrous pieces from dry bulk material.
Magnetic Pulley
Installed as the conveyor head pulley.
A compact choice for continuous ferrous separation at the end of a conveyor without adding a large overhead unit.
Girdap Akımı Ayırıcı
For non-ferrous metals.
Used after ferrous removal when the line also needs to recover aluminum, copper, brass, and other conductive non-ferrous metals.
Anahtar Uygulamalar
Magnetic separation supports both equipment protection and product purity in recycling and industrial material handling.
Plastik Geri Dönüşüm
Removes screws, staples, wire, steel fragments, and tramp iron from PET, HDPE, PP, PE film, and rigid plastic recycling lines.
Waste Sorting
Recovers ferrous metal from municipal solid waste, RDF/SRF preparation, and mixed material recovery facilities.
Mining & Quarrying
Separates iron-bearing material and protects crushers, screens, and conveyors from unwanted metal contamination.
Üretme
Metal çıkararak rendirmeler, makineler ve üretim hatlarını çalışır durumda tutar.
Selection & Operating Factors
Good separation depends on more than magnet strength. The material flow and installation position matter just as much.
What to Check Before Selection
- Material type, bulk density, particle size, and moisture level.
- Expected ferrous contamination size, shape, and loading rate.
- Conveyor width, belt speed, burden depth, and installation height.
- Whether the plant needs manual cleaning, automatic discharge, or continuous operation.
Neden Önemlidir?
In plastic recycling, a small steel fragment can damage crusher knives, screens, pelletizer components, or extruder screws. A properly placed magnetic separator reduces this risk before the metal reaches expensive downstream equipment.
For higher purity targets, magnetic separation is often used before density separation, air classification, optical sorting, or pelletizing.
Typical Technical Parameters
Final specifications depend on the separator type and the recycling line layout. These parameters are common discussion points during equipment selection.
| Parametre | Tipik Seçenekler | Seçim Notları |
|---|---|---|
| Separator Type | Overband, drum, pulley, eddy current | Match the type to material flow, metal type, and discharge requirement. |
| Conveyor Width | Customized to line width | The magnetic zone should cover the full material stream. |
| Material Layer Depth | Low and evenly spread is preferred | Deep burden reduces capture performance, especially for small metal pieces. |
| Temizleme Yöntemi | Manual or automatic discharge | Automatic discharge is preferred for continuous and high-contamination lines. |
| Installation Position | Above conveyor, at discharge, or head pulley | Place the separator before sensitive machinery whenever possible. |

Sıkça Sorulan Sorular
Demir ve çelik gibi ferromanyetik metallerin aşağıdaki makineleri zarar verebileceği zaman, çöpe, granülatörler, extruderler, pelletizatörler veya ince sınıflama ekipmanlarının önüne kurun.
No. Standart manyetik ayırıcılar demir ve çelik gibi ferromanyetik metalleri kaldırır. Alüminyum, bakır ve bronz genellikle manyetik dalga akım ayırıcısı gerektirir.
Overband manyetikler konveyörlerin üzerinde yaygındır. Düzenli ferromanyetik atık çıkışı gerektiren küçük ve sürekli düzenler için çanak manyetikler ve manyetik kızaklar kullanışlıdır.
Manyetik kuvvet, bant hızı, yük derinliği, malzeme dağılımı, montaj yüksekliği ve partikül boyutu, yakalama performansını etkiler.
Derecesine bağlıdır. manyetik ferritik ve martensitik (400 serisi) çelik manyetik alanı hisseder, ancak manyetik olmayan austenitik (300 serisi) çelik standart manyetik ayırıcıya neredeyse görünmez ve manyetik akım veya sensör tabanlı sınıflandırma gerektirir.
Magnetik kuvvet uzaklıkla hızla düşer, bu yüzden ayırıcı yeterince yakın yerleştirilmelidir ki alanı malzeme katmanının altına ulaşsın. Derin veya dengesiz bir yük, veya çok yüksek monte edilmiş bir manyetik, küçük ferromanyetik parçaların geçmesine olanak tanır. Doğru boşlukta derin ve dengeli bir akış, en güvenilir yakalama sağlar.
