Rare Earth Roll (RE) Separators

May 2, 2012

With the ever-increasing demand for high-purity feedstocks used in manufacturing, Eriez offers its Dry High-Intensity Rare Earth Roll Magnetic Separators. These provide maximum efficiency in the separation of weak magnetic particles for product purification applications. Eriez applied sophisticated finite element analysis in magnetic circuit design to produce an energy-free separator capable of generating the exceptionally high field strengths needed to remove unwanted fine iron contaminants.


Magnetic cleaning has been applied to the most basic industry foundations such as industrial minerals, metals recycling, glass batch and cullet, abrasives and refractories, chemicals, pharmaceuticals, and plastics.

  • High-intensity magnetic roll assembled from rare earth permanent magnets
  • Magnetic roll diameters of 4, 6, and 12 in. (10, 15, and 30 cm)
  • Magnetic roll widths up to 60 in. (1.5 m)
  • Continuous duty applications treating up to 12 TPH feed/separator
  • All stainless steel construction
  • Variable speed drive on each magnetic roll
  • Mounted spread box/hopper and vibratory feeder
