I. Based on the source of magnetic force, they can be divided into permanent magnet iron separators and electromagnetic iron separators.
Permanent magnet iron separators rely on high-performance rare-earth permanent magnets to generate a magnetic field, while electromagnetic iron separators generate a magnetic field using energized coils.
The main advantages of permanent magnet iron separators are that they require no electricity, have strong and stable magnetic force, simple structure, and are easy to maintain.
The characteristics of electromagnetic iron separators are that their magnetic force can be adjusted by current control, requiring continuous power supply and a cooling system; temperature rise will affect the magnetic force.
II. Based on the iron unloading method, they can be divided into manual iron unloading and automatic iron unloading.
Manual iron unloading iron separators have a simple structure, are windproof, rainproof, and corrosion-resistant, but require periodic power outages for iron removal. Self-unloading iron separators have a built-in belt drive, eliminating the need for power outages and manual unloading, ensuring continuous automatic operation and automatically separating and throwing the adsorbed iron pieces into a collection box. Compared to manual iron unloading, self-unloading iron separators have a more complex structure and are more expensive.
Self-unloading iron separators are mainly suitable for production lines with thick material layers, large iron pieces, and a high degree of automation.
III. Pipeline-type Magnetic Separator: Directly connected in series in a closed pipeline, fully sealed, with no dust leakage; requires shutdown for cleaning.
Suitable for pipelines conveying powdery, granular, or slurry materials.
IV. Oil-cooled and Air-cooled Electromagnetic Separators: Generate a magnetic field using an energized coil, employing oil circulation or forced air cooling for superior heat dissipation compared to natural cooling. Allows for long-term operation and stable magnetic force. More complex structure, requiring more stringent maintenance.
Suitable for high-temperature environments and continuous high-power operation.
