Learn how Hengci Technology’s RCDD Self-Cleaning Overbelt Magnetic Separator delivers continuous, automatic iron removal with self-cooling and self-unloading features for mining, cement, and power industries.
Discover how the RCDD Self-Cleaning Overbelt Magnetic Separator and self-cooling self-unloading electromagnetic iron removers from Hengci Technology Co., Ltd. ensure efficient, automatic iron separation for mining, cement, and power industries.
Introduction
In modern bulk material handling industries, efficient removal of ferrous impurities is essential to protect equipment and ensure product purity. The RCDD Self-Cleaning Overbelt Magnetic Separator is one of the most advanced and widely used electromagnetic iron separators in industrial applications today. With self-cooling, self-dumping, and automatic discharging features, it provides continuous, stable, and reliable magnetic separation performance for conveyor systems in cement plants, mining operations, and power generation facilities.
1. Understanding the RCDD Self-Cleaning Overbelt Magnetic Separator
The RCDD self-cooling self-unloading electromagnetic iron remover is a type of self-dumping electromagnetic iron separator installed above a conveyor belt. It is specifically designed to attract and automatically discharge ferromagnetic materials such as iron pieces, bolts, and tramp metal from bulk materials like coal, cement, minerals, and aggregates.
Unlike traditional manual-cleaning separators, the RCDD model integrates self-cooling and automatic iron discharge mechanisms. This combination enables continuous operation without production interruption, ensuring high efficiency and minimal maintenance.
2. Working Principle
The working principle of the RCDD Self-Cleaning Electromagnetic Separator is based on electromagnetic induction and mechanical automation. When energized, the internal coil generates a powerful magnetic field that penetrates the conveyor belt and attracts ferrous materials within its range.
Once captured, the self-unloading belt system automatically carries the trapped iron particles to the side of the separator, where the magnetic field gradually weakens, allowing the ferrous impurities to be discharged into a designated collection bin.
The self-cooling electromagnetic system ensures that the device operates at optimal temperature, preventing overheating and extending the magnet’s lifespan. In harsh industrial environments, this cooling system is crucial for maintaining consistent magnetic performance.
3. Key Features and Technical Advantages
The RCDD series self-cooling self-unloading electromagnetic iron remover offers a range of innovative features:
● Self-Cooling and Self-Unloading Design: Uses circulating oil or air-cooling systems to dissipate heat efficiently, ensuring stable operation even under continuous duty.
● Fully Sealed Construction: Dustproof, waterproof, and corrosion-resistant design enhances durability and performance stability.
● Automatic Iron Discharge: The self-dumping belt removes collected ferrous materials automatically, minimizing manual labor.
● High Magnetic Penetration Depth: Enables efficient separation of tramp iron from thick material layers or deep bulk flow.
● Low Maintenance: With fully sealed bearings and automatic tension adjustment, the separator ensures long-term reliability.
4. Types and Models Available
Hengci Technology provides several specialized models to meet diverse industrial needs:
1) RCDD Self-Cleaning Electromagnetic Separator for Belt Conveyor

Performance, Advantages, and Selection Guide for RCYD Series Magnetic Iron Separators
The RCYD series permanent magnet self-unloading iron remover, representing the latest in magnetic separation technology, is an automatic magnetic iron separator that combines high magnetic force, continuous operation, and durability—it adopts NdFeB permanent magnets (with high coercive force and stable magnetic performance) and works as a belt type separator to automatically discharge ferrous materials, enabling uninterrupted, manual-intervention-free operation ideal for heavy-duty environments like ore conveyors, cement plants, and mining sites. Its key advantages include a self-cleaning design (reducing downtime for conveyor belts), automatic iron discharge (ensuring continuous productivity), energy efficiency (no power needed for magnetization, unlike electromagnetic models), and durability (withstanding high temperatures and dust-laden conditions). When selecting this separator, factors like conveyor width/speed, material flow rate, iron content/particle size, and installation height should be considered, with available configurations including RCYD type, suspension type, and manual type— the RCYD series self-unloading model is preferred for high-capacity operations, while the manual type is a cost-effective choice for smaller systems—and it can be used as an iron separator, belt conveyor magnetic separator, or overband magnetic separator, seamlessly integrating with existing conveyor systems as reliable iron removal equipment.
