Eddy current separators
THE SOLUTION FOR THE EXTRACTION OF NON-FERROUS METALS: DRAGOELECTRÓNICA EDDY CURRENT SEPARATORS
Since 1975, Dragoelectrónica has been designing and manufacturing eddy current separators for the extraction and separation of all types of non-ferrous metal such as aluminium, copper, zinc or brass in material treatment processes where this type of non-ferrous metal can be found.
Separation of non-ferrous metals from ferrous metals for classification
Sorting technologies are important for conserving resources and the circular economy.
In many industrial processes where contamination by both ferrous and non-ferrous metals may exist, it is necessary to use the eddy current metal separation system that detects and extracts non-ferrous metals that a permanent magnet or electromagnet is not capable of. The most common situations for the use of this technology can be:
Once the ferrous metals have been extracted, eddy currents separate the non-ferrous metals from the rest of the waste.
Extraction of heavy non-ferrous metals
In the recycling of wood, municipal solid waste (extraction of cans), glass, plastic, incineration ashes.
Metal slag recovery
For the separation of aluminium, copper, bronze and any other non-ferrous metal.
How does an eddy current separator work
An eddy current separator consists of a small magnetic head drum conveyor, constructed with high gradient magnets: Neodymium, Iron, Boron that rotates at high speed. This system of poles, together with the rotation, generates its own magnetic field that causes the separation of the inert material in a different parabola, the result of which is the separation of metals such as aluminium, zinc or brass. Dragoelectrónica manufactures several models of eddy current separators: with concentric or eccentric inductor drum, with a number of poles that make up the inductor drum depending on the fraction of the material to be separated. In this way, our wide range of machines can be adapted to the different needs of the customer.
