The Mag Spring® Magnetic Grate Separator (also known as a grate magnet grid) is designed for the efficient removal of tramp iron from powders, granules, and bulk materials.
Built with high-intensity rare earth neodymium bars and a stainless-steel grate housing, it ensures maximum magnetic separation performance while maintaining a hygienic, easy-clean design.
Available in round, square, or rectangular frames, magnetic grates can be installed in hoppers, chutes, drawers, ducts, and pipelines to capture even the smallest ferrous particles.
Food Processing & Grain Handling – Sanitary grate magnets for hygienic bulk handling systems and powder lines.
Chemical & Pharmaceutical Production – Permanent magnetic grates remove metal impurities from granular chemicals and pharma ingredients.
Plastics & Recycling Lines – High-intensity grate magnet grids protect feeders and extruders from metal damage.
Powder Processing & Additives – Industrial magnetic grate separators for bulk solids feeder protection.
Chute & Hopper Installations – Drawer-type grate magnet separators capture ferrous contaminants in vertical material flows.
Mag Spring® Magnetic Grate is a high-intensity grate magnet separator designed for efficient tramp iron removal from powders, granules, and bulk materials. Each unit features powerful neodymium magnetic bars enclosed in a durable stainless steel grate, forming a reliable barrier that captures even the smallest ferrous contaminants.
Engineered for industrial applications, this magnetic grate separator is widely used in food processing, plastic recycling, chemical, grain handling, and pharmaceutical production lines. The easy-clean and sanitary models are especially suitable for hygienic bulk handling systems where product purity and processing safety are critical.
Mag Spring® magnetic grates are available in various configurations — drawer-type, round or square housings, with options for auto-clean or manual-cleaning mechanisms. High-intensity versions, made with rare earth magnets, can achieve surface magnetic strengths up to 8,000–15,000 Gauss, ensuring superior magnetic separation performance for fine powders and viscous materials.
High Magnetic Strength: Up to 12,000 – 15,000 GS using neodymium magnets for powerful separation.
Sanitary & Easy-Clean Design: Polished 304 or 316L stainless steel construction for food-grade safety and quick maintenance.
Custom Configurations: Round or square magnetic grids with flange, threaded, or tri-clamp connections.
Durable Construction: Corrosion-resistant finish for chemical and plastic processing lines.
Temperature Resistance: Special models can withstand temperatures up to 300 °C.
Each unit is engineered to provide long-lasting performance in demanding environments, ensuring minimal contamination and protecting downstream equipment.
