Magnetic separator selection checklist

1. How does your material move?

• Dry powder or granules through a hopper or chute: grate or drawer magnet
• Material on a conveyor belt: overband, suspended plate or magnetic pulley
• Liquid, paste or slurry in a pipe: liquid-line magnetic trap
• Powder or pellets in a pipe or pneumatic line: bullet magnet
• Chute wall, tank or hygiene-sensitive spot: plate magnet
• Small parts, OEM or heat/corrosion duty: NdFeB or SmCo magnet

2. Measure and note

• Opening size, belt width or pipe size
• Hanging height and burden depth (conveyors)
• Material, particle size and flow rate
• Moisture and temperature
• What iron you are finding: rust, wear fragments, tramp iron
• Room around the magnet to reach and clean it

3. Choose the build

• Stainless grade: 304, 316 or 316L (316 / 316L generally suit more corrosive or washdown duty)
• Full weld if you want no screws or crevices (built to order)
• Cleaning method: by hand, drawer pull-out or self-cleaning belt
• Seams and finish you can wipe and inspect

4. Confirm before you order

• Field strength at your working gap (typical rare-earth separators sit around 10,000–13,000 gauss at the pole; plate magnets up to about 10,000 Gauss typical; not a guarantee)
• Temperature limit: NdFeB for normal duty, SmCo for heat and corrosion
• Written spec with size, grade and build
• Which documents your quality system needs (ask at quotation)
• Who cleans and inspects it, and how often

5. Send it

• Photo of the spot: one wide, one close, with a ruler for scale
• This list, filled in as far as you can
