EDDY CURRENT NON-FERROUS METAL SEPARATORS PERMANENT RARE EARTH MAGNETIC Removes non-ferrous metallics from: • plastics • glass cullet • electronic scrap • automobile shredder residue (ASR) • boiler bottom ash • spent foundry core sand • municipal solid waste (MSW) • co-mingled recyclables • urban wood waste • mixed metals. SB-780P • Stronger eddy current fields. Eriez draws upon its expertise in magnetics to develop a more powerful separator than competitive units • Each eddy current non-ferrous separator designed for your application. Single–source dependability and overall system integrity • Utilizes a high–gradient Erium® 3000 Rare Earth permanent, non–electric magnetic rotor element for significant power savings. Erium 3000 is over 5 times stronger than conventional permanent magnets FEATURES & BENEFITS In 1969, Eriez Magnetics patented both permanent magnetic and electromagnetic eddy current separators. These powerful systems feature improved permanent magnetic circuits with Rare Earth Erium® 3000 for stronger eddy currents and improved separation of non–ferrous materials. In operation, the non–ferrous separator utilizes permanent rare earth magnets to induce eddy currents into metallic particles. This produces repelling forces which separate the metallics from non–metallics, providing a cleaner product for further processing. Removal of the metallics is selective and product loss is minimized. ONLY FROM ERIEZ

2 PRINCIPLES OF OPERATION The non–ferrous metallic separator consists of an external drum, an internal permanent magnetic rotor, a drive, and belt conveyor. The external drum shell of non–metallic composite material rotates at conventional belt conveyor speed. The internal concentric full diameter Rare Earth alternating polarity rotor turns at much higher RPM than the external shell. Through the induction of eddy currents and the resulting repelling forces, the alternating magnetic field selectively repels the non–ferrous metals and physically separates them from other materials with...

3 ECS-12" REA, Laboratory Separator Used for testing and pilot plant work. Lexan sides allow full viewing. ECS-48" REO, Type HD with HV Pan Feeder Removing aluminum cans from municipal solid waste (MSW) at a material recovery facility. Typical Eddy Current Separator Control, NEMA 4 construction, with rotor logic and VFD for Eddy conveyor belt. ECS-24" REO, Standard Removing aluminum from glass cullet. ECS-24" REA, Type PET with Hopper and Feeder Removes small aluminum contaminants and purifies PET (plastic) flakes. An RE Roll Magnet fitted to the right side removes weakly magnetic...

4 EDDY CURRENT SEPARATOR MODELS TYPE “M” EDDY This streamlined design is ideal for material recovery facilities (MRF). It uses rugged 8-inch steel channel frame and legs, compact reinforced tapered hood, washdown motors, quick 20–second removable access panels, Lexan viewing window, and URO urethane conveyor belt. It can be equipped with FE or REA rotors. Eriez’ pan feeders, chutes, and variable speed belt and rotor options are available. Inboard or outboard drives are available. The control is NEMA 12 with rotor logic and motor starters. THE “STANDARD” EDDY This is the Eddy all others are...

6 The Eddy Current Rotor is the heart of the separator. Eriez builds four different rotor designs: ferrite, Rare Earth arched (REA), Rare Earth Original (REO), and Super Eddy, for a multitude of applications Now, rotors are available as separate items. All Eriez rotors use patented Kevlar/ceramic tile surface shells and grease retainer chambers. They typically are balanced to operate at 2500 RPM. FERRITE (FAST EDDY) This is the most economical rotor. While it uses conventional barium ferrite magnets, they are type 8C, the strongest available. It is ideal for separating aluminum, used...

8 APPLICATION DATA AUTOMOBILE SHREDDER RESIDUE (ASR) After car bodies are shredded, Drum, Belt, and Pulley Magnets remove the ferrous and Eddys are used to remove the remaining non–ferrous metals (NF). The ECS can recover 95% of the NF and raise the grade/purity from ~50% to 85-90%+. ALUMINIUM USED BEVERAGE CANS (UBC) Recycling awareness has led many communities to build Material Recovery Facilities (MRFs) to recycle glass, plastic, paper, steel and aluminum. Belt, Pulley, and Drum Magnets remove the steel (tin cans), and Eddys remove the aluminum UBCs. This is more cost effective than...

9 APPLICATION DATA (continued) PET PLASTICS Polyethylene terephthalate (PET) is a plastic material used in beverage containers. The PET containers are shredded and washed. Special Eriez’ Eddys remove small metal contaminants to purify the PET, so it can be re–used to make fiber, banding, or blended to make ‘recycled content’ containers. FOUNDRY SAND Hi–tech non–ferrous foundries, like aluminum, often use binders or resins in the sand cores. Spent sand cores do not go granular, so they cannot be separated in a delumper. The ECS repels the metal from the sand core chunks. The sand can be...

10 OTHER ERIEZ RECYCLING EQUIPMENT MAGNETIC PULLEYS Powerful axial interpole magnetic circuits separate ferrous from recycled products being conveyed on belt conveyors. Also used to remove ferrous prior to the Eddy Current. SUSPENDED ELECTROMAGNETIC SEPARATORS Automatically reclaims ferrous from product flows on conveyor belts or vibratory feeders to provide a salable product and/or protect downstream equipment.
