What Is a Permanent Magnetic Separator And How Does It Work?

A permanent magnetic separator is a specialized device that uses permanent magnets to generate a stable, long-lasting magnetic field—no external power supply required—to separate ferrous materials from non-ferrous materials in industrial processing.

Ruijie Suspension (Hanging) Permanent Magnetic Separators is one of the types of Permanent Magnetic Separator machine that usually mounted above shaking tables, conveyors, or hoppers to capture fine iron powder or small ferrous particles from flowing materials.

How Does the Suspension Permanent Magnetic Separators Work?

Step-by-Step Working Process

The Hanging separator's operation follows a simple, continuous cycle, perfectly integrated with equipment like shaking tables (a common setup in mining or recycling):

Step 1: Material Feeding & Flow

Raw materials (e.g., ore particles, recycled aggregates, or incineration bottom ash) are fed onto the underlying equipment—for example, a shaking table. The table vibrates to stratify materials by density: lighter non-ferrous materials (e.g., sand, aluminum) move toward the edge, while heavier particles flow steadily across the table's surface.

Step 2: Magnetic Field Capture

As the material stream passes directly below the suspended permanent magnet, the magnet's strong magnetic field penetrates the material layer. Ferrous contaminants (even fine iron powder as small as 0.1mm) are instantly attracted to the magnet's surface, breaking away from the non-ferrous material flow.

Key detail: The magnetic field's strength is calibrated to avoid attracting non-ferrous metals (e.g., copper, aluminum) or non-metallic materials, ensuring precise separation.

Step 3: Contaminant Removal (Cleaning)

Once ferrous debris accumulates on the magnet's surface (visible as a layer of iron particles), the cleaning mechanism activates:

Manual cleaning: For low-throughput scenarios (e.g., small-scale processing), operators use a dedicated scraper to periodically wipe off the iron debris, which is then collected for recycling.

Automatic cleaning: For high-throughput systems (e.g., Ruijie's industrial-grade separators), a motor-driven brush or conveyor belt runs along the magnet's surface, automatically stripping off iron contaminants and depositing them into a collection bin—no need for manual intervention.

Why Choose Ruijie's Separators?

Ruijie's Suspension Permanent Magnetic Separators stand out for three key reasons:

Customization: Tailored to fit specific shaking table dimensions and material throughput, ensuring optimal magnetic field coverage and separation efficiency.

Durability: Built with high-grade permanent magnets and rugged casings, they withstand prolonged use in dusty, wet, or high-vibration environments.

Synergy with Other Systems: Designed to integrate seamlessly with Ruijie's broader range of sorting equipment, including eddy current separators and screeners, creating end-to-end solutions for material purification and resource recovery.

In summary, Suspension Permanent Magnetic Separators are indispensable for removing fine iron powder and ferrous contaminants in material processing. Ruijie's commitment to precision engineering and system integration makes their separators a top choice for industries seeking efficiency, reliability, and high-purity outputs.
