Stainless Steel Magnetic Grate Separators
– Product Highlights
The Stainless Steel Magnetic Grate Separators (also commonly referred to as industrial magnetic grills or grids) are highly efficient permanent magnetic separation systems engineered to extract fine ferrous impurities from various processing lines. These versatile units feature high-performance magnetic rods securely mounted within a rigid stainless steel framework, allowing them to operate continuously without secondary material contamination or electrical energy consumption. Designed for seamless integration, they can be easily positioned at any critical point in the production flow where dry powders, granular materials, liquids, or thick slurries pass through. This makes them an exceptionally reliable, efficient, and maintenance-free solution for cross-sectional ferrous contaminant separation.
– Working Principle
Stainless Steel Magnetic Grate Separators function by projecting a powerful, dense magnetic field across the entire path of material flow via high-flux permanent magnetic tubes. As raw materials flow or drop through the grid structure by gravity or pneumatic pressure, any present ferrous contaminants, rust particles, and fine mechanical wear are instantly diverted toward the surface of the rods and securely held there. This reliable physical gripping mechanism completely isolates harmful metal pieces from the active product stream, ensuring excellent final product purity and preventing downstream machinery blockages.
Product Information
Structure and Materials
Every Stainless Steel Magnetic Grate Separator manufactured by MagnetGlobal is constructed using a heavy-duty stainless steel support frame paired with multiple high-intensity magnetic rods. Each integrated rod consists of a seamless, heavy-wall stainless steel tube enclosing an internal, high-performance permanent magnetic core. The magnetic bars are aligned in a parallel layout at precisely calculated geometric intervals to optimize the balance between material flow velocity and magnetic capture depth. The specific spacing between these bars can be fully customized according to the particle characteristics of your material, whether handling fine cohesive powders, free-flowing granules, or large bulk materials. For extreme purity requirements, multi-layer staggered configurations are available to provide complete, gap-free magnetic coverage across the entire material stream. These standard magnetic grills are heavily utilized across global industries, typically installed directly at the gravity feeding inlets or discharge outlets of injection molding machinery, industrial dryers, hoppers, and automated material handling equipment.

Features and Mechanical Reliability
The robust structural integrity of our Stainless Steel Magnetic Grate Separators relies entirely on premium SUS304 or SUS316L stainless steel framing paired with industrial-grade permanent magnets. This rigid mechanical assembly is specifically built to withstand constant physical material impacts and continuous equipment vibrations without structural deformation. Operating completely on permanent magnetic principles, this design requires no electrical power wiring or control cabinets, eliminating the risks of electrical failure or sudden power-loss contamination. This creates an extremely energy-efficient, stable, and highly dependable system suited for uninterrupted 24/7 industrial operations.

Technical Parameters and Flexible Specifications
Our standard product line includes versatile models such as the MG-100 for laboratory or low-flow applications up to the heavy-duty MG-300 designed for continuous high-output production lines and high-contamination environments. The grate diameters range from 100 millimeters to 300 millimeters, housing between 3 to 13 high-intensity pipes across dual layers. These models accommodate hopper capacities from 12 kilograms up to 250 kilograms and are compatible with inlet diameters spanning 140 millimeters to 600 millimeters. While standard models utilize cylindrical magnetic bars, specialized streamlined or teardrop-shaped profiles can be integrated upon request to further minimize material resistance and eliminate flow stagnation.

Key Advantages
1. Strong Magnetic Attraction
The magnetic rod surface strength ranges from 6,000 to 14,000 Gauss, enabling effective removal of not only large ferrous particles such as iron scraps and nails, but also fine iron powder and weakly magnetic stainless steel particles.
2. Full Magnetic Coverage with No Blind Spots
Through optimized rod arrangement and precise spacing control, the magnetic field fully covers the cross-section of the material flow, preventing iron particles from passing through the gaps between rods. This results in significantly higher separation efficiency compared to conventional magnetic separators.
3. Low Operating Cost and No Consumables
This permanent magnetic system requires no electricity or consumable parts. Magnetic performance remains highly stable with minimal magnetic decay even after 5–10 years of normal use. Cleaning is simple, requiring only manual wiping, with no recurring costs for parts replacement.
4. High Installation Flexibility
Magnetic grills are available in suspended, drawer-type, and insert-style configurations, and can be installed directly at hopper outlets, pipelines, or conveyor discharge points without welding, cutting, or modifying existing equipment.
5. Durable Construction and Long Service Life
The robust stainless steel frame provides excellent structural strength, allowing the grill to continuously withstand material impact and equipment vibration without deformation or damage.
6. Low Flow Resistance and Wide Temperature Range
Cylindrical magnetic rods (teardrop-shaped rods also available on request) feature smooth surfaces that reduce material resistance and prevent blockages.
Standard operating temperature is ≤80°C, with a maximum of 350°C. Customized temperature ratings are also available based on specific material conditions.
Applications Target Applications and Industrial Value
These high-performance Stainless Steel Magnetic Grate Separators provide essential contamination control across the plastics, food processing, pharmaceutical, chemical, animal feed, and agricultural grain industries.
