Eddy Current Non Ferrous Metal Separator Plant

The MAGQUIP Eddy Current Separator plant is a two-metal product standalone fully integrated metal separation plant which is able to produce both ferrous and non-ferrous metal product streams in a small footprint area.

The plant is a combination of MAGQUIP Eddy Current separator with “EccentriSort” rotor and an Axial Pole Ferrous metal permanent magnet drum separator which will yield very clean metals product.

The combined magnetic equipment and vibrating feeder are integrated onto a modular skid frame to form a complete metal separation solution of easy deployment into any facility and can even be supplied as a mobile version for easy movement around material recycling facilities.

The eddy current separator is a critical piece of equipment in any modern recycling plant where non-ferrous metal such as aluminium or copper and ferrous metals 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 when deployed in a huge range of applications.

The Axial pole permanent rotary drum separator can be supplied with ferrite magnets for easy to separate material or in a rare earth version for “fine” metal separation application.

Mixed material is fed via a hopper, or conveyor belt onto the MAGQUIP vibrating pan feeder where it is conveyed to the axial pole drum magnet. The drum magnet separator is lace underneath the discharge end of the vibrating feeder and will attract any ferrous metals in the product stream. These ferrous metals are then held to the drum surface by the magnetic force and then discharged from the drum at a position where the permanent magnet segment in the drum no longer influence the particles. They then fall off into a dedicated ferrous metal product chute. Non-ferrous metal and any other material found with the product stream are then centrifugally discharged from the drum separator into a chute which feeds the eddy current separator module belt.

The material is then presented to the eddy current separator eccentric rotor where non-ferrous electrically conducting metals such as copper and aluminium are ejected from the belt into a splitter module with the use of adjustable diverting plate. The non-ferrous metal “throws” end up separated into a dedicated product chute.

The non-conducting materials such as plastic, rubber and organic matter that are separated, end up being thrown centrifugally into a “drops” chute unaffected by the eddy current rotor.

Since MAGQUIP uses an Eccentric type of rotor that can handle relative amounts of ferrous metal without inducting heating issues, any ferrous metal not separated at the initial axial pole drum separator stage has final chance of separation via the rotor and will also end up in dedicated secondary ferrous metal collecting chute.

Recover very clean and pure ferrous and 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

This metal separator plant uses the MAGQUIP axial pole drum separator to yield excellent recovery of ferrous metals and the EccentiSort eccentric rotor produce high rate of pure non-ferrous metal separators.

The Magquip “Eccentric” rotor has the following advantages:

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