Rotary Magnetic Separator

       After the material enters the equipment chamber through the feed inlet, it passes under the rotating magnetic rod assembly by gravity. Driven by a motor, the magnetic rod assembly rotates at low speed, continuously generating a high-intensity magnetic field (up to 14,000 gauss) while gently tumbling and dispersing the material to prevent agglomeration and bridging. As the material traverses the rotating magnetic field, ferrous contaminants such as iron filings, iron powder, and welding slag are firmly adsorbed onto the surface of the magnetic rods, while the clean material flows smoothly through the gaps and is discharged, achieving a continuous, dynamic ferrous contaminant removal process. Depending on the configuration, the unit can perform manual intermittent cleaning or automatic scraper-based iron discharge, thereby meeting diverse production continuity requirements.

Features and Advantages

• Prevents arching and blockages: The rotating magnetic system continuously turns, effectively disrupting powder agglomerates and significantly reducing the risk of clogging and bridging.
• Enhanced iron removal efficiency: The rotating design increases the frequency of contact between the material and the magnetic field, making subsurface ferrous impurities more readily exposed and captured.
• Stable operation and broad adaptability: Suitable for standard dry powders as well as powders with poor flowability or slight agglomeration, meeting the demands of complex production environments.
• Permanent magnet construction, energy-efficient operation: Equipped with a high-performance NdFeB permanent magnet assembly, it requires no excitation power supply; only the drive motor consumes energy, resulting in low operating costs and simple maintenance.
• Compact structure, easy maintenance: Featuring a quick-release design, the magnetic rod assembly can be fully withdrawn for cleaning, ensuring convenient maintenance and suitability for continuous production lines.
