| titleOfInvention | Process and apparatus for sorting reusable pieces of raw material |
| abstract | The invention relates to a process and an apparatus for sorting reusable pieces of raw material (5), which are continuously moved in a conveying direction (2) by a transporting device (1), wherein an analysis of the chemical composition of the pieces of raw material (5) is performed with the aid of laser-induced plasma spectroscopy (LIBS) and, dependent on the composition determined, an automated sorting of the pieces of raw material (5) is carried out, wherein in a first step the pieces of raw material (5) are subjected to multiple first laser pulses (6), in order to remove surface coatings and/or contaminants from the pieces of raw material (5), and in a second step one or more second laser pulses (7) are directed onto the locations of the pieces of raw material (5) from which the surface coatings and/or contaminants have been removed, wherein exposed material of the pieces of raw material (5) is transformed into a plasma by the second laser pulses (7), wherein the same laser (3) is used for the first and second laser pulses (6, 7) and the area of the pieces of raw material (5) over which the first laser pulses (6) are moved and which are freed of surface coatings and/or contaminants is greater than the area of the pieces of raw material (5) that is exposed to the second laser pulses (7), wherein the focal diameter and the focal point of the laser beam are kept constant between the first and second laser pulses (6, 7). In this way, an unfalsified analysis of the composition of the pieces of raw material (5) can be achieved by using only one laser and, dependent on the analysis, a sorting can be performed. |
