Eddy Current Non Ferrous Metal Separator

The MAGQUIP “EccentriSort” Eddy Current Separator is a critical piece of equipment in any modern recycling plant where non-ferrous metal such as aluminium or copper must be separated from any waste or product stream.

The Eddy Current Separator is a non-ferrous metal separator system using an eccentrically orientated high-energy rare-earth rotor as opposed to the concentric type of rotor. This specially engineered high-speed rotor sets the performance benchmark for Eddy Current separators and has been proven technology that has been deployed in a huge range of applications.

MAGQUIP is also able to produce a “Fines” Eddy Current Eccentric rotor for smaller more difficult to separate particles less than 5 mm in size.

Electrically conductive particles introduced into a rapidly changing magnetic field produced by very strong Rare Earth (NdFeB) magnets have circulating electric currents induced in them – so called “Eddy Currents”.

The rapidly changing magnetic field is enabled by the rare earth magnet rotor rotating at very high speeds of 2800-3000 rpm. These swirling electrical eddy currents produce a magnetic field in the non- ferrous conducting particles. The reaction of the two “like pole” magnetic fields, opposing one another from the rotor and the induced particle produce a repulsion force on the particles

The repulsion force is added to the momentum from the belt travel to throw conductive particles forward from the drum. Non-conductive particles follow their normal trajectory; ferrous particles travel around the drum and fall from the belt.

The short belt conveyor system had a belt driven by a motorised pulley. Material travelling along the belt once repelled and ejected from the rotor, is thrown into a non-ferrous metal chute with any non-conducting material continuing along its natural trajectory from the belt.

Recover very clean and pure non-ferrous metals from granulated waste products, size range 5 to 200mm (fines version will separate less 5mm).

Typically, it is used in the processing of:

Scrap Metal and Cable Recycling
Metal separation
Rejects from shredder plants
Glass Cullet
Household refuse
Can sorting
E-Waste
Metal slag mixtures

Using the “EccentiSort” eccentric to rotor produce high rate of pure non-ferrous metal.

The Magquip “Eccentric” rotor has the following advantages:

High throughput and separation efficiency
Simple feeding arrangement
Unrestricted particle size (Fine type rotor available less 5mm particles)
Easy belt change via cantilevered frame assembly
Will handle relatively high amounts of ferrous metal as opposed to concentric type without particle inductive heating causing belt and rotor cover damage
