Drawer Magnets are designed with multiple durable magnetic tubes to effectively eliminate small to medium-sized ferrous contaminants from free-flowing product streams, thereby enhancing product integrity and protecting processing machinery across various industries such as food and beverage, pharmaceuticals, plastics, chemicals, recycling, and mining. They are the preferred method for capturing fine ferrous tramp metal in medium flows and can handle a variety of separation tasks in mechanical or gravity flow applications. As products flow through the housing, they cascade over staggered magnetic tubes, allowing ferrous contaminants to adhere to the magnets and be drawn away to prevent wash-off. MPI offers different types of drawer magnets for specific processing needs, including high-throughput systems, precision contaminant removal, gravity-fed applications, and hygienic environments. Their commitment to innovative design and performance has made MPI a leader in permanent magnet separators, with various sectors relying on their drawer magnets for the protection of products and equipment.

Carbon Steel and Stainless-Steel Drawer Magnets are designed with extremely durable carbon or stainless-steel housings and provide effective tramp metal protection for plastic injection molding and extrusion machinery, especially in applications with high levels of tramp metal in plastic regrind materials. These magnets remove ferrous metal impurities from dry, free-flowing materials in gravity-fed systems, offering a robust and cost-effective solution for safeguarding processing equipment and maintaining product integrity.
MPI's Continuous Clean Drawer Magnets are designed to efficiently remove small to medium tramp metal from dry powders and granules in gravity-fed chutes. Featuring four tiers of staggered 1-inch rare earth magnetic tubes, the system enhances filtration and prevents clogs. Its continuous cleaning mechanism allows for uninterrupted product flow, utilizing pneumatically controlled cylinders to extract accumulated metal without pausing the filtering process. The magnetic tubes retract through a stripper assembly, which automatically separates and collects metal contaminants into a designated discharge area. This setup minimizes downtime and maintenance while safeguarding processing equipment and ensuring product quality.
MPI's Self-Clean Drawer Magnets are engineered to capture small metal contaminants in gravity-fed chutes, protecting equipment during milling and mixing while maintaining product quality. They feature dual tiers of 1-inch high-intensity rare earth magnetic tubes arranged in a staggered layout for optimal interaction with the product stream, effectively removing ferrous tramp metal without bridging. The system includes an automated self-cleaning mechanism that requires minimal manual effort; as materials pass through, tramp metal is attracted to the tubes, which pneumatically retract through a stripper assembly to dislodge and collect contaminants. This ensures continuous operation, lessening maintenance requirements and reducing production downtime.
MPI’s Inline Quick-Clean Drawer Magnets offer effective magnetic separation of ferrous contaminants from dry, free-flowing materials in both pneumatic and gravity-fed systems. With a design focused on user convenience, the quick-clean feature enables operators to safely and efficiently extract collected metal, minimizing downtime. These drawer magnets are particularly suited for the food, plastics, chemical, and powder processing sectors, aiding in equipment protection, enhancing product quality, and adhering to industry safety standards, all while facilitating maintenance and optimizing process uptime.
MPI’s Inline Self-Clean Drawer Magnets automate the removal of ferrous contaminants from dry, free-flowing materials in pneumatic and gravity-fed systems.
