Rare Earth Roll (RE) Separators


Rare Earth Roll (RE) Separators provide peak separation efficiency and ensure exceptional product purity. These powerful separators are ideal for many industries, including mining, plastics, abrasives, recycling, glass, foundries, industrial minerals, metals, electronics and more.  RE Rolls are constructed with neodymium-boron-iron rare earth permanent magnets, an extremely powerful magnetic material with at least ten times the attractive force of conventional magnets. The high gradient magnetic circuit includes a variety of proprietary items designed to produce a magnetic field in excess of 21,000 gauss. These highly magnetic rolls are capable of recovering weakly magnetic particles, and will handle feeds from one-half inch (13 mm) to very fine materials. 

Eriez RE Rolls are available in three, four and six inch diameter rolls. Roll widths range from five to sixty inches. A unique cantilever design allows quick belt replacement, requiring only one operator. The standard belting is Teflon coated, graphite filled KEVLAR with thickness of five and ten mils. Optional FDA-approved belting is available for food and pharmaceutical applications. Eriez' RE Roll Separators are available in single, double and triple stage versions with either non-magnetic or magnetic-rerun. Eriez experts are available to help customers select the right design for their particular application.
