Eddy Current Separators utilize powerful Rare Earth magnets arranged into a high speed, composite shelled, rotor.

Eddy Current Separators utilize powerful Rare Earth magnets arranged into a high speed, composite shelled, rotor. PET flake and plastic regrind containing non-ferrous contaminates such as aluminum is fed onto a conveyor belt in a controlled, low density, thin layer. The belt then passes over the rotating magnets and eddy currents are created in the aluminum. When the polarity of the magnetic field around the aluminum is the same as the rotating magnets, the aluminum is repelled from the magnet. This causes the trajectory of the non-ferrous metal to be different than the plastic. The two streams of material are separated by an adjustable splitter in a simple, high volume and effective manner.

PET bottle, carpet and packaging producers demand high purity, post consumer, recycled plastic to reduce material costs and support their environmental sustainability goals. Our latest Eddy Current Separators deliver exceptional non-ferrous metal separation from PET flake and bottles. You can obtain a single pass aluminum flake reduction up to 92% and achieve a clean PET yield of 97% to 99%. Beyond the benefits of high purity consider that a 1% improvement in yield can save your company up to $250,000 / yr in recycled PET with a 60” wide Eddy Current Separator.

Equipment Features & Benefits

The Rare Earth Arched Rotor is even effective “popping” small aluminum particles.
Our new, high speed bearing design allows a 25% higher rotor speed for exceptional purity.
The rotor can be operated in forward or reverse, accommodating different particle characteristics.
Eriez Eddy Current rotors are high tension, carbon fiber wrapped for low vibration and long life.
A special splitter provides exceptional straightness for optimum plastic purity and yield.
The splitter is adjustable in both angle & height to satisfy a range of belt speeds & particle sizes.
PET flake process rates up to 2500 lbs/hr/ft of feeder width can be achieved.
A 1.3 mm thin, abrasion resistant urethane conveyor belt maximizes the aluminum “pop”.
A vibratory feeder assures a controlled flake depth to enhance the separation performance.
The controls are housed in a NEMA 4 enclosure and include a belt speed tachometer.
