High-Intensity Rare Earth Magnetic Design
MPI Magnetic Belt Feeders seamlessly integrate precision material handling with high-efficiency magnetic separation, making them an ideal solution for applications where both consistent product flow and contaminant control are critical. These systems incorporate a high-intensity magnetic separator directly beneath a durable, continuously moving belt, enabling simultaneous product feeding and automatic removal of ferrous contaminants such as stainless-steel fragments, work-hardened steel, and embedded metal. Designed for demanding environments in industries like food processing, recycling, pharmaceuticals, plastics, and general manufacturing, MPI’s Magnetic Belt Feeders ensure uniform product delivery while capturing even weakly magnetic materials that standard pulleys may miss. The high-gauss rare earth magnet circuit provides superior surface attraction, ensuring contaminants are held securely and removed efficiently, protecting downstream equipment and maintaining high product quality standards. Compact, efficient, and customizable to fit your unique processing needs, these feeders reduce labor, minimize downtime, and increase throughput—all while operating with minimal maintenance. Whether you're feeding granules, flakes, powders, or small parts, MPI Magnetic Belt Feeders deliver consistent, contaminant-free performance with every cycle.

Magnetic Belt Feeder Product Details
MPI’s Magnetic Belt Feeder is a dual-function system that combines precise product feeding with high-efficiency magnetic separation. The unit features a durable conveyor belt that runs over a powerful, high-intensity rare-earth magnetic plate. This design enables the feeder to consistently regulate the flow of material while simultaneously removing ferrous contaminants, including weakly magnetic metals such as stainless steel, work-hardened steel, and embedded particles.
Here’s how it works step by step:
Material Introduction
Bulk material is evenly fed onto the moving conveyor belt, either manually or via upstream process equipment. The feeder is designed to maintain a controlled, uniform product flow.
Magnetic Separation Zone
As the material travels along the belt, it passes directly over a high-gauss rare earth magnetic plate. This plate is located beneath the belt and spans a critical section of its length, creating an intense magnetic field at the surface.
Ferrous Contaminant Capture
The magnetic field penetrates through the belt to attract and hold ferrous particles present in the product stream. This includes fine or weakly magnetic metals that may be embedded within the product or difficult to detect with standard magnetic equipment.
Material Discharge
Non-magnetic, clean product continues along the conveyor path and is discharged from the end of the belt. Since the magnetic field does not affect these materials, they remain unaffected and exit freely.
Contaminant Removal
Captured ferrous contaminants are held tightly against the belt until they move out of the magnetic field zone. At that point—typically near the return side of the belt or through a designated discharge path—the magnetic grip is released, and the metal falls into a separate collection chute or bin.
Continuous, Automatic Operation
The entire process runs automatically and continuously, requiring no operator intervention. The design eliminates the need for manual sorting or stopping the production line, thereby reducing downtime and labor requirements.
Optional Enhancements
Optional features such as variable speed drives, custom belt widths, and integrated controls can be added to meet specific application needs and enhance separation efficiency.
By integrating feeding and separation into a single, compact, and self-contained system, MPI’s Magnetic Belt Feeder delivers unmatched efficiency, consistency, and protection for downstream equipment, making it an invaluable asset in any process that demands both precision and purity.
