Magnetic Rotary Feeder
 |
- 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 silicone
- 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
|
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.
