Recycling Plants Separation, Sorting Lines, Material

Non-ferrous metals can be separated from the conveying stream by an eddy current. In this case, many permanent magnets are arranged on a fast-rotating deflection roller, which in turn generates a high frequency magnetic field. With this, the induced currents in the non-ferrous metals counteract their origin and thus push off these material parts.
