Eriez P-Rex Rare Earth Scrap Drum

Processing Equipment

For the ultimate in metal recycling, the Eriez P-Rex™ Rare Earth Scrap Drum cannot be beat, literally. It is the strongest Permanent Drum Magnet on the market and up to 40% stronger than standard Electro Drum Magnets. Remove small ferrous particles as well as heavy metal spheres, referred to as meatballs or knuckles, which often contain valuable nonferrous metals and represent the most difficult type of object to capture.

Eriez’ innovative Permanent Rare Earth Xtreme™ Drum Magnet, P-Rex™ is a historic breakthrough in ferrous separation. P-Rex’s powerful permanent magnetic circuit designed using sophisticated modeling techniques is up to 40% stronger than an electro and is capable of moving large spherical objects at twice the distance!

Current electromagnetic drum technology simply is not capable of sustaining a deep enough magnetic field to attract much of the “heavy spherical” ferrous during scrap metal processing. These heavy spheres, referred to as meatballs and knuckles, often contain valuable nonferrous metals and represent the most difficult type of object to capture magnetically.

While P-Rex™ maintains a constant strength profile, all electro drum magnets are subject to significant strength loss due to heat gain. Electro drum magnets typically lose around 30% strength within three hours of start up!

Eriez P-Rex Drum Magnet removes meatballsA Magnet’s Toughest Challenge

Spheres are the most difficult objects to capture magnetically. Add to that in scrap processing many of these objects contain nonferrous metals and wire making magnetic attraction even more difficult. P-Rex™ is up to the challenge…
able to reach into the shredded material and remove even these difficult meatballs.





“The P-Rex drums are everything Eriez says they are and more. We could not be happier with them. We have been running them for a year now and have had zero issues.” – Rob Weber, Garden Street Iron & Metal
