5. Grill Magnet: Reliable for Fine Particle Removal
Grill magnets are designed to remove fine ferrous particles from free-flowing materials. They are widely used in industries requiring high levels of purity.
Key Features:
- High-intensity magnetic rods.
- Easy installation in chutes and hoppers.
- Low-maintenance design.
Applications:
- Ensuring purity in recycled food packaging materials.
- Removing fine metal contaminants from powders and granules.
- Protecting downstream equipment in recycling facilities.
6. Roller Magnet: Precision for Fine Ferrous Removal
Roller magnets are engineered for separating fine ferrous materials during the processing of bulk materials. Their high-intensity magnetic rollers ensure efficient separation.
Key Features:
- High-gradient magnetic rollers.
- Adjustable separation settings.
- Suitable for high-volume operations.
Applications:
- Removing fine ferrous materials from e-waste.
- Enhancing purity in mineral recycling.
- Processing plastic waste for reuse.
7. Overband Magnetic Separator: Ensuring Continuous Metal Removal
Overband magnetic separators are widely used in Kenya’s recycling industries for continuous removal of ferrous metals from conveyor belts. These separators are mounted above conveyors and operate automatically, ensuring uninterrupted material flow.
Key Features:
- High-intensity magnets for effective separation.
- Suitable for high-capacity operations.
- Adjustable installation height for versatility.
Applications:
- Sorting ferrous metals from municipal solid waste.
- Removing contaminants from shredded plastics.
- Enhancing purity in construction and demolition waste recycling.
Conclusion
Kenya’s recycling industries are setting benchmarks by incorporating advanced magnetic separators. These technologies not only enhance material recovery rates but also contribute to environmental sustainability. By adopting the right magnetic separation equipment, recycling facilities in Kenya can achieve greater efficiency, cost savings, and product purity.
