Eddy Current Separator

Eddy current separation devices are an effective way of removing non-ferrous metals from other products. Application such as aluminum cans from municipal waste, aluminum flakes from shredded PET, brass and aluminum from foundry sands and metals from shredded automobile scrap, other metals such as lead can also be removed. For successful non-ferrous separation, a magnetic should be installed prior to an Eddy Current Separator.

OPERATION PRINCIPAL

Eddy Current Separator is read to be installed for separation .This separator utilizes a powerful Eddy Current Rotor, Conveyor Belt, two variable discharge areas and support frame. This optional vibratory feeder provides a consistent flow of material to the Eddy Current Separator.

The main principal is that an electrical charge is induced into a conductor by changes in magnetic flux cutting through it. Moving permanent magnets passing a conductor generates the change in flux.

Eddy Current Separator is designed according to the principal that conductor can generate induced current in the high frequency alternating magnetic field.

A strong high-frequent magnetic alternating magnetic field generate on the surface of the sorting roller when it works ,then when conductive non-ferrous metal pass through the magnetic field, eddy current will be induced in the body of non-ferrous metals.

The eddy current itself will generate the opposite direction magnetic field ,non-ferrous metals(such as aluminum, copper etc.) will leap forward along its transport direction by the performance of magnetic field repulsion son as to separate other non metallic substances and achieve the purpose of sorting .

The main distinguishing criterion is material conductivity and density ratio values, a high percentage of the value of the material more easily to separated than the lower material.

EDDY CURRENT ROTOR

Eddy Current Rotor uses an alternating magnetic field to produce electrical current in conductive metal .The electrical current generates its own magnetic field around an object which posses an magnetic field from the Eddy Current.

The repulsion diverts the object from the product stream .Mass, conductivity and density influence the force and distance an object will repel.

WORKING OF EDDY CURRENT ROTOR

Eddy current is based on the use of magnetic rotor with the alternating polarity, spinning rapidly inside a non-metallic drum driven by a conveyor belt.

As non-ferrous metals pass over the drum the alternating magnetic field creates eddy current in non-ferrous metal particles repelling the material away from the conveyor.

While other materials drop off at the end of the conveyor, the non-ferrous metals are propelled forward over a splitter for separation.

EDDY CURRENT SEPARATION SYSTEM

Eddy Current Separation System encompasses all the equipment above the necessary to separate non-ferrous metals and add ferrous metal separation equipment

It is important to remove ferrous metal prior to exposure to the Eddy Current Separator.

Ferrous metal is attracted and held by the strong magnetic force. The non ferrous metal will heat up and could burn holes in the belt and cause significant to the Eddy Current Rotor.
