The Eriez innovative P-Rex® and eP-Rex Drum Magnets represent great advancements in magnetic circuit design achieving ferrous recovery rates beyond what is possible with standard electromagnet drums. Electro drum magnets have always been stronger than permanent magnetic drums, until now, and thanks to Eriez.
P-Rex’s powerful permanent magnetic circuit, designed using sophisticated modeling techniques, is up to 40% stronger than an electromagnetic drum 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 magnet field to attract much of the “heavy spherical” ferrous during scrap metal processing. These heavy spheres, referred to as meatballs or 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 electros are subject to significant strength loss due to heat gain… typically around 40% within three hours of start up! The P-Rex is much stronger and keeps that strength permanently.
P-Rex® Benefits:
- 40% Stronger during operation
- Significantly wider pick-up zone
- Edge-to-Edge performance
- No heat induced strength loss
- Agitates and flips ferrous
- Optional retractable jaw

A 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 wire such as copper, 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.
