Eriez updates RevX-E eccentric eddy current separators

The units promise to be maintenance-friendly.

November 23, 2021

Eriez’s newest eccentric eddy current separator, the RevX-E, gives customers high-quality performance in a more maintenance-friendly package, according to the manufacturer.

Chris Ramsdell, separation and recycling product manager for Erie, Pennsylvania-based Eriez, says the company consulted with recycling customers and designed the RevX-E to meet their needs. “We consistently heard the same demands from customers: They wanted high power with low maintenance, minimal downtime and a longer service life. We delivered on all these points with our RevX-E eddy current separator.”

Eriez’s RevX-E features an eccentrically mounted magnetic rotor within a nonconductive shell for separating nonferrous metals. The rare earth rotor produces a powerful field focused at the end of the belt, the manufacturer says.

“We thought a lot about ease of maintenance when developing this machine,” Ramsdell says.

The RevX-E’s updated design takes up less floor space and incorporates a cantilevered frame that enables maintenance staff to change the belt in less than 10 minutes. A new hood with an adjustable splitter allows operators to handle nonferrous materials in varying sizes and ensures optimum separation. Large access panels all around the machine are designed to facilitate entry for maintenance. Units also include direct drive for both the rotor and conveyor.

The RevX-E is available in the ST22 and LT2, which are manufactured on the same eddy current separator framework. Ramsdell says the only difference between the ST22 and LT2 is the magnet configuration on the rotor assemblies.

The ST22 features a 22-pole rare earth eccentric rotor and is designed to handle fine materials that are less than 1 inch. This rotor option offers a high pole change frequency for the removal of fine nonferrous metals from shredded plastics, such as polyethylene terephthalate (PET) bottles, the company says.

The LT2 features an eight-pole rare earth eccentric rotor and is designed to handle 1-inch and larger coarse materials. Eriez says this rotor option offers a deep, high-powered eddy current field that allows for the removal of larger nonferrous metals, such as crushed aluminum cans from a PET bottle stream.
