Abstract
The invention relates for separating different electrically conductive particles, especially of waste materials, by means of an eddy-current separation, whereby the supplied particles to be separated are cooled. The invention also relates to an eddy-current separator provided for carrying out said method. The separator has a rotational magnet system and a transport system for guiding the particles to be separated along the magnet system. A cooling chamber through which the particles are guided is located immediately upstream from the magnet system. The conductivity of the non-iron metallic particles is increased by cooling thus allowing differential separation of these materials.
Claims5
A device for separating non-ferrous metal particles of different electrical conductivity comprising:
- a first transport system, comprising a cooling chamber having an input end and an output end through which said particles to be separated from one another are conveyed;
- a second transport system having first end at said output end of said cooling chamber and an second end opposite from said first end, moving said particles in a linear first direction from said first end to said second end;
- a magnetic eddy-current separator, disposed beneath said second transport system between said first end and said second end over which said cooled particles are transported, said eddy-current separator comprising a rotatable magnetic system having a rotational axis;
- and
- at least one collection container deposed alongside said second transport system.
