Magnetic Rotary Feeder

Magnetic Rotary Feeder
  1. 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
  2. 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.
  3. 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
  4. 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
  5. 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 silicone
  6. Adjustable Spring-Loaded Control Gate
  7. Removable Inspection Cover
  8. Tramp Metal Collection Tray:
    • Attachment: Removable cantilever tray
    • Locking notch prevents the tray from vibrating loose
  9. Self-Clean Model Available:
    • Automated cleaning, easy inspection, and maintenance

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.
