Eriez continues to provide trusted technical solutions to the recycling, packaging and processing industries.
In 1969, Eriez patented both permanent magnetic and electromagnetic eddy current separators. Today, these powerful systems feature improved permanent magnetic circuits with rare earth magnetic material for stronger eddy currents and improved separation of nonferrous materials.
In operation, the nonferrous separator uses permanent rare earth magnets to induce eddy currents into metallic particles. This produces repelling forces that separate the metallics from non–metallics, providing a cleaner product for further processing. Removal of the metallics is selective and product loss is minimised.
The nonferrous metallic separator consists of an external drum, an internal permanent magnetic rotor, a drive, and a belt conveyor. The external drum shell of non–metallic composite material rotates at conventional belt conveyor speed. The internal rare earth alternating polarity rotor turns at a much higher revolutions per minute (RPM) than the external shell.
Through the induction of eddy currents and the resulting repelling forces, the alternating magnetic field selectively repels the nonferrous metals and physically separates them from other materials with minimum product loss.
Eriez’ RevX-E Eddy Current Separators feature an eccentrically mounted magnetic rotor within a non-conductive shell for the separation of nonferrous metals. The rare earth rotor produces a powerful focused field at the end of the belt.
Advantages of the RevX-E Eccentric Eddy include a cantilevered frame design for quick conveyor belt changes (10 minutes); rack and pinion splitter adjustment for simple and precise splitter placement for optimum separation; large access panels all around the machine allow easy maintenance access; the compact design requires less space; and direct drive rotor and direct drive conveyor.
It is available in three sizes – one metre, 1.2 metres and 1.5 metres. Two rotors are offered – the LT2 Rotor Assembly, an eight pole earth eccentric rotor for coarse (+2.54 centimetre) size fractions, and the ST22 Rotor Assembly 22 pole rare earth eccentric rotor for fractions from 0.6 centimetres to 2.54 centimetres.
Eriez’ Ultra High-Frequency Eddy Current Separator recovers ultra-fine aluminium, copper, and other nonferrous fines materials typically missed on traditional eddy current separators from automotive shredder residue.
The UHF Eddy’s combination of a rotor designed to produce high gauss at the belt’s surface, with many magnetic poles operating at higher rpms, creates ultra-high-frequency changes resulting in superior separation of fine nonferrous and even bare copper wire.
This UHF Eddy provides an economical solution to improve zorba recovery without the need for additional expensive sensor-based or optical sorting equipment.
Each one metre unit ships with an Eriez Brute Force feeder to provide even distribution of material across the width of the conveyor. It recovers bare copper wire and other valuable nonferrous metals as small as two to three millimetres.
Features include an ultra-high-frequency rotor, high surface gauss for superior separation, a large number of frequency changes, the rotor spins at higher RPMs, a carbon fibre shell and precise rack and pinion splitter adjustments.
The rotor is a UHF 32 pole rare earth eccentric rotor for fine (less than 1.905 centimetre) size fractions.
