Eriez 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, industrial minerals, and more. RE Rolls are constructed with neodymium-boron-iron rare earth permanent magnets, an extremely powerful magnetic material with at least 10 times the attractive force of conventional magnets, notes the company. 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 ½-in. (13 mm) to very fine materials. RE Rolls are available in 3-, 4-, and 6-in. diameter rolls. Roll widths range from five to 60 in. 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 10 mils.
