Neodymium Magnetic Filter Rods (12000 Gauss)

Structure and Materials

 

Our Neodymium Magnetic Filter Rods (12000 Gauss) (also known as a magnetic bar or magnetic tube), which are also widely recognized by industry procurement managers as round Magnetic Bars, serve as the absolute technological cornerstone of modern industrial separation systems, making this heavy-duty magnetic tube ideal for extracting hazardous ferromagnetic contaminants from raw bulk materials. The outer protective casing is fabricated from premium-grade, fully welded SUS304 or SUS316L stainless steel, enclosing a high-performance magnetic core composed entirely of high-coercivity neodymium (NdFeB) rare-earth permanent magnets.
The internal magnetic core typically consists of an intricate alternating stack of precision-machined cylindrical magnetic elements and high-permeability magnetic flux guiding plates. Through this optimized magnetic circuit design, the localized surface magnetic strength can be engineered to reach up to a maximum of 15,000 Gauss. The seamless stainless steel tube provides uncompromised physical protection for the internal core while ensuring effortless maintenance and rapid manual cleaning, easily satisfying the strict sanitary and compliance requirements of the international food processing, pharmaceuticals, and fine chemical sectors.

Key Advantages of MagnetGlobal Technology

 

1. High iron removal efficiency

Equipped with high-performance magnets providing 6000–15000 Gauss magnetic strength, these heavy-duty Magnetic Filter Bars can efficiently capture fine ferromagnetic contaminants and microscopic iron dust, significantly improving separation efficiency and reducing downstream equipment wear.

 

2. Customization capability

We precisely tailor our Neodymium Magnetic Filter Rods in custom diameters and lengths to meet your specific filtration requirements. They can be integrated into existing pipelines or automated processing systems and are perfectly suitable for powders, granules, and liquids.

 

3. Low operating cost

Our permanent Tube Magnets require no external electrical power, ensuring an exceptionally long service life with minimal maintenance. The corrosion-resistant and smooth stainless steel surface allows easy cleaning, ensuring long-term stable performance and exceptionally low operating overhead.

 

4. Safe and environmentally friendly

This passive physical separation process utilizes premium Rare Earth Magnetic Rods that completely prevent secondary contamination in product streams. The system introduces no chemical agents, making it the perfect food-grade magnetic separator choice for sanitary and hygiene-sensitive manufacturing applications.

 

 

Flexible Installation Options

 

Select the optimal installation methods based on your specific application environment and material flow characteristics to ensure maximum physical contact between materials and the magnetic rod for ultimate separation performance.

 

1. Embedded installation

These industrial Magnetic Bars are installed horizontally inside material pipelines or gravity-fed hoppers. As raw materials pass through the grid, ferromagnetic contaminants are securely captured on the rod surface. This method is highly suitable for powders, granules, and liquid solutions.

 

2. Suspended installation

The magnetic filter rods are securely suspended directly above conveyor belts or open discharge points. During continuous material flow, tramp iron contaminants are attracted upward and retained, requiring simple periodic manual wiping. This setup is ideal for heavy bulk materials.

 

3. Drawer-type installation

Individual magnetic filter rods are pre-assembled into modular, multi-tier drawer-type magnetic grates for rapid removal and cleaning. This user-friendly design is widely specified in automated food processing and pharmaceutical production lines with strict hygiene requirements.

 

4. Portable operation

Individual permanent magnetic rods can be manually utilized for localized batch separation within small containers, packaging bins, or test hoppers, providing a highly flexible solution for temporary or mobile purification applications.
