The RCDFJ series forced oil circulation self-cleaning electromagnetic separator, engineered by Weifang Hengji Electromagnetic Machinery Co., Ltd., sets a new standard for demanding industrial applications. This advanced overbelt magnetic separator features a patented forced oil cooling system that enables continuous high-capacity operation beyond conventional limits.

Integrating oil-cooling technology with automated cleaning, these robust electricity magnets deliver unparalleled performance in high-volume, high-dust environments. The RCDFJ series excels in large-scale thermal power plants, major coal preparation facilities, and metallurgical processing systems. This premium overbelt magnetic separator maintains consistent magnetic performance under extreme conditions, ensuring continuous protection for downstream machinery while providing maximum reliability for non-stop operations.

Exceptional Magnetic Performance
Utilizing a DT4 electrical pure iron core and multi-layer oxidized copper wire coils, this overbelt magnetic separator achieves a 150mT magnetic field with 40% higher attraction force than standard models. Its unique dual cooling pipe system maintains coil temperatures below 65°C, ensuring consistent performance from these powerful electricity magnets.

Intelligent Cooling System
The system features a dedicated oil circulation pump (≥25L/min flow rate) and an integrated axial fan array with temperature monitoring. Automatic alarm protection safeguards these overbelt magnetic separator units during continuous operation.

Fully Automated Cleaning
Equipped with a crowned drive drum and cycloidal reducer motor (IP55 rated), this overbelt magnetic separator offers adjustable belt speeds from 0.15-0.25m/s. The integrated rubber scraper ensures efficient material discharge from these advanced electricity magnets.

Military-Grade Reliability
Featuring fully sealed cast steel bearing seats (IP6X protection) and vacuum-encapsulated Class F insulation coils rated to 155°C, these electricity magnets deliver exceptional durability. The bellows-type oil conservator provides automatic volume compensation for long-term reliability.

The RCDFJ overbelt magnetic separator operates through an integrated system combining electromagnetic separation with advanced thermal management:

Electromagnetic Separation System
A rectifier cabinet converts 380V AC to DC220V power, energizing the excitation coils to generate powerful directional magnetic fields. These sophisticated electricity magnets utilize DT4 magnetic poles to form closed magnetic circuits, maximizing separation efficiency as ferrous materials are extracted from conveyed bulk loads.

Oil Circulation Cooling
Heated oil is pressurized through the system into tubular condensers, where axial fans provide forced air cooling (air volume ≥3000m³/h). This advanced thermal management maintains optimal operating temperatures for the overbelt magnetic separator, with oil temperature differentials controlled within 8°C for consistent performance.

Automated Cleaning Process
Captured ferrous materials are continuously transported via cleaning belt to collection points. The PLC system automatically initiates cleaning cycles at preset intervals (15-60 minutes adjustable), ensuring uninterrupted operation of these high-capacity electricity magnets in demanding industrial environments.

Energy Sector
In coal-fired power plants, the overbelt magnetic separator processes up to 3000t/h in coal handling systems, effectively removing metal contaminants. These powerful electricity magnets also serve coal preparation plants for medium recovery in dense medium separation processes, ensuring operational efficiency and equipment protection.

Metallurgical Industry
The system handles sintered ore conveyor separation with high-temperature versions rated for environments up to 80°C. This heavy-duty overbelt magnetic separator integrates into blast furnace raw material pretreatment systems, where these advanced electricity magnets safeguard critical downstream equipment from ferrous contamination.

Special Applications
At bulk port terminals, the overbelt magnetic separator coordinates operation with bucket wheel reclaimers for continuous metal extraction. In waste-to-energy plants, these reliable electricity magnets purify RDF fuel streams, protecting processing machinery while maintaining consistent throughput in challenging material handling applications.
