+86 -13559234186The magnetic bar utilizes rare earth permanent magnet steel as its magnetic source, is encased in high-quality 304 or 316L seamless stainless steel tubing, and is welded and sealed at both ends. Its powerful magnetic force separates fine ferromagnetic impurities from various powders, granules, and slurries, improving material purity, ensuring equipment integrity, and enhancing product quality. The magnetic bar can be fixed individually to feed ports, discharge ports, or conveyor pipelines, or it can be used in complete sets of magnetic screens, drawer-type iron removers, fluid iron removers, and rotary iron removers.

In industrial production and precision manufacturing, efficiently and thoroughly removing ferromagnetic impurities from raw materials has always been a core challenge in ensuring product quality and maintaining equipment safety. While traditional bar magnets are widely used, their right-angled design can lead to clogging and magnetic blind spots. Today, an innovative design is quietly changing this landscape: the permanent teardrop-shaped magnet. Its superior performance has made it the preferred choice for numerous industries seeking ultimate efficiency.
What is a permanent teardrop-shaped magnet?
As the name suggests, a permanent teardrop-shaped magnet is made from high-performance rare earth materials such as neodymium iron boron (NdFeB). Its outer protective casing (typically 304 or 316 stainless steel) is designed with a streamlined teardrop-shaped cross-section. This isn't just for aesthetics; every curve reflects profound engineering ingenuity, designed to address inherent pain points of traditional magnets.
Product Details
1. The magnetic rod surface is welded, sealed, and polished from SUS304, SUS316, or SUS316L steel pipe. It can handle dry powders, wet materials, or liquids.
2. The surface magnetic field strength of a 25mm diameter magnetic rod can reach over 12,000 gauss.
3. The surface is mirror-polished to meet food and pharmaceutical hygiene standards.
4. Magnetic rods can be customized to specific specifications. Length, diameter, and shape (such as square or rectangular cross-sections) can also be customized. Plugs and accessories of varying shapes and functions can also be customized to meet specific needs.
5. The default operating temperature is 80°C, but products with operating temperatures up to 350°C can be provided for special requirements.
6. The ends of the magnetic rods can be customized with threaded holes, screws, eyelets, tapered tips, and other features.
What are the strengths of the teardrop-shaped design?
1. Unobstructed and smooth flow, completely eliminating clogging
* Traditional pain points: Square or round magnetic bars tend to accumulate at the rear when handling powdered or granular materials, especially when handling moist, sticky materials, requiring frequent machine downtime for cleaning.
* The teardrop-shaped solution: The unique streamlined body acts like a stream of water, allowing materials to pass smoothly and without dead ends. This significantly reduces the risk of bridging and blockages, ensuring continuous and efficient production line operation.
2. Strong magnetic force, more efficient capture
* The teardrop-shaped tip design concentrates and evenly distributes the magnetic field lines in key areas (i.e., the front and sides of the material flow), creating a powerful "magnetic capture zone." Compared to traditional magnetic bars, it more effectively captures fine, weakly magnetic iron filings, improving iron removal efficiency by over 30%.
3. Self-cleaning, extremely low maintenance costs
* With virtually no material residue, cleaning is exceptionally simple. In non-metallic pipes, impurities on the magnetic rod's surface are easily removed with a simple pull due to its smooth surface and concentrated magnetic force, significantly reducing worker workload and equipment maintenance downtime.
4. Durable and Long Service Life
* The core is made of the highest-grade permanent magnet material, resulting in extremely slow magnetic force decay and providing a stable magnetic field for over ten years. The sturdy stainless steel casing is fully welded and hermetically sealed to withstand harsh environments such as high pressure, high temperature, and high humidity. It is completely corrosion-resistant and leak-proof, meeting food and pharmaceutical-grade hygiene requirements.
What industries are it widely used in?
This revolutionary permanent teardrop-shaped magnetic rod is a "quality guardian" for numerous industries:
* Food and health product industry: Used to protect production lines, ensuring that powdered sugar, flour, starch, milk powder, tea, and other products are free of iron contamination, complying with stringent HACCP and FDA certifications.
* Chemical and plastics industry: Used to remove rust and metal impurities from pigments, masterbatches, and plastic granules, protecting precision extruders and molds and improving finished product quality.
* Pharmaceutical industry: Ensures the production safety of APIs, traditional Chinese medicine powders, and preparations, eliminating the risk of metal contamination and meeting GMP standards.
* Ceramics and glass industry: Protects expensive grinding equipment, preventing iron in raw materials such as kaolin and glazes from affecting product whiteness and quality.
* Recycling and building materials industry: Used to separate and recover metal impurities from waste plastics, wood chips, sand, and gravel.
