The Rotary Magnetic Separator is a high-efficiency magnetic separation unit designed to remove fine ferrous contaminants from powder, granule, and light viscous materials. With high-intensity neodymium magnetic bars arranged in a rotating frame, this separator ensures maximum magnetic contact with material flow, capturing even micrometer-sized iron particles without bridging or blockage. Continuous Rotation to Prevent Material Clogging.
The rotary design is essential for materials that exhibit poor flowability, ensuring compliance with strict industrial standards such as the HACCP food safety protocols by effectively removing fine ferrous contaminants.
In industries such as food, plastic, chemical, and pharmaceutical processing, iron contamination can compromise product quality, reduce equipment lifespan, and affect process efficiency. The rotary magnet separator offers a simple yet effective solution.
Its rotating magnetic bars continuously move through the material flow, preventing material bridging and ensuring every particle passes close to the magnetic surface. This guarantees efficient capture of ferrous impurities in powders, granules, and slightly sticky substances such as sugar, flour, resin, or chemical powders.
The high-intensity magnets reach up to 12,000 Gauss, providing strong holding force for reliable separation in various industrial applications.
This rotary magnetic separator is a manual cleaning model. After a production cycle, operators can easily pull out the magnetic drawer to remove the captured iron particles by hand.
Simple operation
Minimal moving parts for long-term durability
Low maintenance costs
Ideal for small-scale or batch production
Manual cleaning also allows quality-control teams to inspect captured contaminants, helping identify sources of iron contamination in production lines.
The separator housing is made of stainless steel 304 or 316L, offering excellent corrosion resistance and hygiene standards for food and chemical environments.
Surface finish options: mirror-polished (sanitary) or bead-blasted (industrial)
Inlet/outlet connections: square or round, customizable to existing pipelines
Typical connection sizes: Φ150 mm – Φ300 mm
Optional high-temperature magnets for drying or baking lines
These features ensure the separator fits a variety of production setups while maintaining high separation performance.

The primary challenge in handling fine or cohesive powders—such as starch, cellulose, or ultra-fine plastic resins—is their tendency to bridge or clog when passing through traditional static magnetic grates. Our Rotary Magnetic Separator is specifically engineered to overcome this mechanical resistance.
Inside the stainless steel housing, a high-intensity magnetic grate (up to 14,000 Gauss) continuously rotates at a controlled speed. As the material flows into the inlet, the rotating action effectively breaks up clumps and prevents “bridging” at the entry point. This ensures that every particle is exposed to the magnetic tubes. The powerful Neodymium (NdFeB) magnetic circuit creates a high-gradient field that captures even the finest para-magnetic particles and weak magnetic stainless steel scales. While the purified powder flows freely through the discharge outlet, the captured contaminants remain held on the rotating tubes, significantly reducing the maintenance frequency required for static units.
