Magnetic separator magnetic filtering Goudsmit Magnetics

Magnetic separators with bar/rod magnets (magnetic fingers) have an extremely powerful yet less deeply penetrating magnetic field. They are therefore best suited for trapping small ferrous contaminants and even weakly magnetic (e.g. cold worked stainless steel) contaminants as small as 30 m out of bulk streams in filling openings and pipelines.
