Structure and Working Principle of Iron Separators（除铁器结构和工作原理）

一、（Core Structure）

1. （Shell）

• Material: Welded from Q235 steel plates; stainless steel is optional for specific working conditions, featuring excellent mechanical strength and corrosion resistance.
• Function: Protects the internal magnetic circuit system and electrical components from dust, moisture, impact, and other external influences. Optimizes heat dissipation design to maintain stable temperature during long-term operation.

2. （Magnetic Circuit System）

• Core Components: Magnetic poles, core tube, excitation element (armature coil for electromagnetic iron separators; neodymium-iron-boron/samarium-cobalt permanent magnets for permanent magnetic iron separators).
• Design Features: Magnetic poles are made of high-permeability materials. The magnetic circuit is optimized to ensure concentrated magnetic field strength (up to 8000-15000Gs) and strong penetration, effectively adsorbing ferromagnetic impurities of different particle sizes.

3. （Cooling System）

• Type: Air cooling (natural ventilation/forced air cooling), water cooling (circulating water cooling); selected based on equipment power and working conditions.
• Function: Rapidly dissipates heat generated by electromagnetic coils or permanent magnets during operation, preventing magnetic performance degradation or equipment failure caused by high temperatures, and ensuring continuous stable operation.

4. Iron Cleaning Device）

• Form: Manual iron cleaning (for small equipment), automatic iron cleaning (scraper type, belt type, roller type).
• Function: Regularly removes iron impurities adsorbed on the surface of the magnetic system, preventing accumulation from affecting magnetic field efficiency, realizing continuous iron removal, and reducing manual intervention.

5. （Auxiliary Systems）

• Power Supply System: Provides stable power for electromagnetic iron separators, supporting voltage regulation to adapt to different working conditions.
• Control System: Equipped with PLC control, fault alarm, and operation monitoring functions, enabling intelligent operations such as automatic start/stop and magnetic strength adjustment.
• Support Structure: Frame, base, and other components ensure stable equipment installation, adapting to different installation scenarios such as belt conveyors and silos.

二、（Working Principle）

1. （Magnetic Field Generation）

• Electromagnetic Iron Separators: After power-on, the armature coil generates a strong magnetic field, whose intensity can be precisely controlled by adjusting the current.
• Permanent Magnetic Iron Separators: High-performance permanent magnets continuously generate a constant magnetic field without external power supply, featuring energy conservation, environmental protection, and stable magnetic field.

2. （Impurity Adsorption）

3. （Iron Impurity Separation）

• Automatic Iron Cleaning Equipment: Through scrapers, iron discharge belts, or roller reversal, adsorbed iron impurities are transported away from the magnetic field area and fall into a designated iron collection device (such as an iron discharge box).
• Manual Iron Cleaning Equipment: After shutdown, manually clean iron impurities adsorbed on the magnetic system surface, suitable for intermittent production or small equipment.

4. （Continuous Operation）

三、（Core Advantages）

• High-Efficiency Iron Removal: High magnetic field strength and strong adsorption capacity, capable of removing ferromagnetic impurities with particle size ≥0.1mm, with an iron removal efficiency of over 95%.
• Stability and Reliability: Structural design adapts to harsh industrial environments; cooling and iron cleaning systems ensure long-term continuous operation of the equipment.
• Intelligence and Convenience: Supports automatic control; some models can remotely monitor operating status with low maintenance costs.
