Eddy Current Separator

Product Description

Power Magnetronics make Eddy Current Separator is an advanced material sorting unit that is capable of separating non-ferrous metals such as aluminium and copper from dry recyclables. Eddy Current Separators are designed to generate eddy currents in high-frequency, alternating-frequency magnetic fields, and to automatically separate non-ferrous metals (aluminum, copper, zinc, etc.) from non-conductive materials. It is widely used in environmental protection industries, like waste classification, waste electrical and electronic equipment recycling, and the treatment of non-ferrous metal industrial materials. The separation efficiency is good for a wide range of non-ferrous metals, which features strong adaptability, and reliable mechanical structure, high efficiency in separation.

Eddy current separator is most suitable for recycling copper, aluminum and other non-ferrous metals from industrial waste and MSW(Municipal Solid Waste). It is designed to tackle and separate non-ferrous metals such as aluminum, copper. They can effectively be used for most applications that need to eliminate non-ferrous materials from the product flow. Nowadays, it's vastly used in the recycling industries of rubbish, automobiles, electronics, and the material processing of non-ferrous metals, etc. Most applications, the Eddy Current Separator is used in line with other separation equipment to ensure a clean recycled product. It has excellent performance on recycling of many kinds of non-ferrous metals.

Working Principle

Material is fed upon the conveyor belt of the eddy current separator, which moves it across the magnetic rotor where separation happens. The magnetic rotor is surrounded by (but not attached to) a wear shell which supports the conveyor belt. This allows the rotor to spin individually and at a much higher speed than the wear shell and belt. When a piece of nonferrous metal, such as aluminum, passes over the separator, the magnets inside the rotor rotate past the aluminum at high speed. This creates eddy currents in the aluminum which in turn produces a magnetic field around the piece of aluminum. The polarity of that magnetic field is the same as the rotating magnet, making the aluminum to be repelled away from the magnet. This repulsion makes the trajectory of the aluminum greater than that of the non-metallic, allowing the two material streams to be separated.
