Eriez rare earth roll (RE) separators provide peak separation efficiency and ensure product purity. These powerful separators are ideal for many industries, including mining, plastics, abrasives, recycling, glass, foundries, industrial minerals, metals, electronics and more, according to the manufacturer.

“Our new and stronger permanent magnetic separators provide a more efficient alternative for handling a wide variety of materials that do not respond well to traditional methods of separation,” said Dave Heubel, director — North American sales. “Our RE roll separators bring together extraordinary magnetic strength and superior product design, enabling this equipment to meet even the toughest customer challenges. These separators are essential in response to new advances in materials and specifications. Increasingly, there is a demand for higher purity feedstocks,” he added.

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 (1.3 cm) to very fine materials.

Eriez RE rolls are available in 4 and 6 in. (10 and 15 cm) diameter rolls. Roll widths range from 5 to 60 in. (12.7 to 152 cm). A unique cantilever design allows quick belt replacement, requiring only one operator. The standard belting is Teflon coated, graphite filled KEVLAR with thickness of 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.
