Drawer Magnets

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.

Manual Quick-Clean Drawer Magnet

MPI Manual Quick-Clean Drawer Magnets feature two tiers of high-intensity rare earth magnetic tubes that ensure the highest levels of magnetic filtration through direct product contact on the tubes, removing ferrous tramp metal from the product stream. The quick-clean mechanism simplifies maintenance by allowing operators to pull out the magnetic assembly, which then automatically wipes off collected metal contaminants into a designated disposal area. This streamlined process reduces downtime and improves operational efficiency while maintaining peak magnetic performance.

1" Continuous-Clean Drawer Magnet

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.

1" Self-Clean Drawer Magnet

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.
