Eriez P-Rex rare earth scrap drums aid in ferrous recovery

Eriez, Erie, Pennsylvania, introduced its P-Rex rare earth scrap drums in 2010, primarily targeting the scrap recycling sector. The company says these units now are operating across North America in a wide variety of recycling sectors in addition to boosting ferrous recovery rates at waste-to-energy and slag recycling facilities.

The company says the P-Rex’s permanent magnetic circuit is up to 40 percent stronger than standard electromagnets and can move large spherical objects at twice the distance. With consistently high magnetic performance from edge to edge, Eriez says it has designed this drum to pull more ferrous objects and facilitates more agitation to remove residual waste, eliminating the need for a cyclone system.

“Whether dealing with diverse materials or a more consistent one, the P-Rex excels,” says Chris Ramsdell, recycling equipment product manager for Eriez. “While each recycling sector uses a unique process designed around its specific feedstocks, the P-Rex can adapt and deliver exceptional ferrous recovery results.”

Waste-to-energy facility operators are now using P-Rex scrap drums to extract metal from the incinerator bottom ash left as a byproduct of combustion, even when those ferrous objects are different shapes and sizes.

Another newer application for P-Rex scrap drums is in slag recycling. This separator has the ability to recover ferrous material from slag, the complex steelmaking byproduct that contains trace and varying amounts of iron, the manufacturer says.

In the scrap recycling sector, Eriez says the P-Rex continues to serve as the central ferrous recovery mechanism within a yard’s shredding and sorting processes. The P-Rex can be integrated as a part of the Eriez CleanStream Process, which incorporates the brute-force power of the P-Rex with the Shred1 ballistic separator, which produces a No. 1 Shred ( less than 0.17 percent copper), and the PokerSort, which extracts troublesome “pokers” from the shred, according to Eriez.
