Custom Square Magnetic Grids
-Product Highlights
The Custom Square Magnetic Grids are heavy-duty, permanent magnetic separation solutions designed to provide exceptional material purification for industrial processing systems. Each unit is precisely engineered with a durable 304 or 316L stainless steel square frame housing high-intensity round magnetic rods arranged in a parallel layout. This geometry allows the grid to fit perfectly into square hoppers, rectangular vertical chutes, and square material pipelines to intercept fine ferrous particulates. Operating with stable magnetic field performance and zero energy consumption, these custom square magnetic grids feature a highly adaptable and separable structure that effectively protects your downstream processing machinery and improves final product purity.
-Working Principle
Custom Square Magnetic Grids function by creating an optimized multi-gap magnetic barrier across the entire cross-section of a square flow path. As dry powders, bulk granules, or aggregates fall through the grid framework by gravity, any present ferromagnetic impurities and fine mechanical wear are immediately deflected toward the high-flux rods. The intense magnetic forces pull the contaminants away from the active product stream and lock them securely onto the underside of the stainless steel bars. This physical trapping mechanism ensures that clean materials pass through unobstructed while hazardous tramp iron is reliably isolated.
Product Information
Structure and Materials
Every Custom Square Magnetic Grid engineered by MagnetGlobal utilizes premium raw materials to withstand the abrasive nature of bulk material handling. The outer frame and protective rod sleeves are crafted from heavy-gauge SUS304 or SUS316L stainless steel, which is continuously seam-welded to prevent any liquid ingress or powder leakage. Inside the rigid tubes, high-grade rare-earth Neodymium (NdFeB) magnetic blocks are aligned with low-carbon steel pole pieces to maximize the localized magnetic flux density. The entire assembly undergoes an industrial finishing process, offering options from sandblasted matte surfaces to high-gloss mirror polishing to meet specific food, chemical, or mining industry standards.
Features and Technical Specifications
A key advantage of selecting our Custom Square Magnetic Grids is the flexibility in matching exact spatial and technical restrictions. The surface magnetic field can be calibrated from a standard 6,000 Gauss for larger-scale tramp iron up to an ultra-high 12,000 Gauss for fine mechanical fragments. The physical dimensions, including frame width, rod spacing, and total bar count, are fully adapted to the flow velocity and particle size of your material. While standard models are rated for temperatures up to 80 degrees Celsius, we provide specialized internal thermal stabilization options that allow the grids to function continuously in high-temperature processing lines up to 350 degrees Celsius.
Key Advantages of MagnetGlobal Design
Our Custom Square Magnetic Grids deliver long-term operational cost savings and superior process safety. Operating as a completely passive permanent magnetic system, they require no electrical wiring, control panels, or recurring energy costs, ensuring round-the-clock protection even during power outages. The fully sealed stainless steel construction provides excellent resistance against oxidation, chemical corrosion, and mechanical impacts, extending the operational lifespan of the grid across decades. Furthermore, the design minimizes product resistance, allowing rapid material flow through hoppers without causing bridging, choking, or structural accumulation.
Target Applications and Engineering Support
These industrial-grade Custom Square Magnetic Grids are widely deployed across global processing facilities to protect high-value downstream assets like extruders, millers, and compounders. They are heavily utilized in plastic recycling plants, pharmaceutical powder blending, chemical processing lines, and grain milling facilities handling sugar, flour, and animal feed. MagnetGlobal offers comprehensive technical consulting and rapid prototyping support. Our engineering team can work directly from your site blueprints or equipment dimensions to develop a customized grid layout, complete with optional mounting tabs, baffle plates, or easy-clean extractor sleeves to fit your production line perfectly.
