Large Tube Drawer Magnet

Ideal for Small Contaminants

MPI’s Self-Cleaning 200 Series Drawer Magnets utilize a “Type A” magnetic circuit, which is ideally suited to capture small contaminants, such as wire, metal shavings and metal wear from dry powder or granular free-flowing product streams in gravity-fed vertical chutes. This Drawer Magnet protects processing equipment, such as milling extruding and mixing, while assuring high product quality standards with automatic magnet cleaning for maximum magnet performance.

Benefits of the Large Tube Drawer Magnet From Magnetic Products, Inc

Self-Clean Drawer Magnet

      1. Magnetic Tubes:
        • MPI 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
      2. Cleaning Cycle:
        • Start: After manually or electrically actuating the solenoid, the cylinders retract, pulling the magnetic tubes through the stripper assembly to deposit the collected tramp iron outside of the product flow area
        • Finish: The cylinders return to the run position, pushing the magnetic tubes back through the stripper assembly into the housing (working position)
      3. Floating Stripper Seal:
        • Adjusts to tube resulting in even wear and longer life between replacements
        • Held in place by machined and fastened laminated stripper plate assembly
      4. Sani-TIGHT Seal™ Gasket:
        • Type: Compression style “O-ring” cord gasket
        • Sealing plate: ½” thick machined stainless plate
        • 100% Positive seal, cannot be over-compressed
        • Sanitary: Gasket can be removed and replaced for wash-down, no adhesive required
      5. Stripper Latch:
        • Releases stripper plate assembly once the plate has been clearly pulled away from the sealing plate
        • Prevents accidental cleaning of the tubes in the product flow area, commonly caused when the stripper assembly is stuck to the sealing plate
      6. Rear Access Panel:
        • For easy inspection and maintenance
      7. Bolt-On Stainless Steel Safety Cage:
        • Removable cover for magnet maintenance and testing
        • Multiple options for tramp metal recovery
      8. Grounding Strap:
        • Provides a discharge path for static buildup
      9. Continuous Automated Self-Cleaning Model:
        • For high-level tramp metal or weakly magnetic tramp metal applications, this system continuously cleans on the go without stopping production

        Large Tube Drawer Magnet Product Details

        How It Works

        The product stream flows through a row of 3″ diameter tubes, then a row of 1” diameter magnetic tubes designed to create an extremely effective magnetic circuit. Each row of magnetic tubes is staggered to prevent bridging or choking of the product stream and to maximize magnetic filtration as product flows through the housing. Tramp metal contaminants are attracted to the magnetic tubes. The pneumatically operated cleaning system safely removes tramp metal from the product stream to a disposal area outside the product flow area.
