Eddy Current Separator

タイトルまたは説明

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 magnet should be installed prior to an Eddy Current Separator.

Eddy Current Separator Principle :
Eddy Current Separator is ready to be installed for separation. This separator utilizes a powerful Eddy Current Rotor, Conveyor Belt, two variable discharge area and support frame. The optional vibratory feeder provides a consistent flow of material to the Eddy Current Separator. The main principle 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 magnetic flux.
Eddy current separator is designed according to the principle that conductor can generate induced current in the high-frequency alternating magnetic field. A strong high-frequent magnetic alternating magnetic field generates on the surface of the sorting roller when it works, thus when conductive non-ferrous metals pass through the magnetic field, eddy current will be induced in the body of nonferrous 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 so 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 is more easily to be separated than the lower material.

Eddy Current Separator Working  :
Eddy current separation is based on the use of a magnetic rotor with 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 currents in the 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.
