Magnetic Rotary Feeder

MPI’S design increases the life of your rolls by evenly distributing contaminant-free feed into your mill! MPI’s Magnetic Rotary Feeder (MRF) is designed to protect and control feeding characteristics of free-flowing materials above hammer mills into processing equipment. MRFs provide a continuous uniform flow of product, increasing processing machinery productivity. The integral permanent plate magnet protects processing equipment from damage caused by ferrous tramp metal. Product feed rates can be regulated with a standard constant speed or an optional variable speed drive system.

  • Premium Upgraded Magnetic Rotary Feeder:
    • Direct OEM replacement
    • Bolt-on design, built to match the inlet
    • Magnet installation is strategically located where the feed of material is most consistently dispersed providing superior magnetic separation before the product enters the mill
  • Effortless Magnet Cleaning System:
    • Exclusive safe, easy-clean magnetic roller glide system properly protects mill from tramp metal
    • The magnet weight rolls on ‘V’ guided roller bearings so that there is virtually no effort needed for magnet cleaning Step 1: Unlatch the plate and pull the handle towards the operator. Stripping mechanism will deposit tramp metal into the collection tray. Step 2: Push handles towards the feeder and re-clamp latches.
  • Stainless Steel Segmented Cup Feeder:
    • Delivers even product distribution to mill for increased operation life between replacements
    • Fabricated from heavy gauge stainless steel for increased wear resistance
  • Powerful 400 Series Ceramic Magnet:
    • Optional rare earth or exclusive hybrid magnet options for increased tramp metal protection
    • Stepped magnet face maximizes tramp metal removal and minimizes tramp metal “wash-off” between magnet cleanings
  • 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
    • Material: FDA approved silicon
  • Adjustable Spring-Loaded Control Gate
  • Removable Inspection Cover
  • Tramp Metal Collection Tray:
    • Attachment: Removable cantilever tray
    • Locking notch prevents the tray from vibrating loose
  • Self-Clean Model Available:
    • Automated cleaning, easy inspection, and maintenance

How Magnetic Rotary Feeders Work:

The feed inlet has a spring loaded control gate which allows large metal objects to pass through the feeder without causing damage, where they are captured by the powerful 400 series strength, Ceramic 8 permanent plate magnet. MPI’s exclusive magnet cleaning system is very simple to operate and requires no heavy lifting or handling during cleaning operation.
