Process and Apparatus for Sorting Reusable Pieces of Raw Material

The invention relates to a process and an apparatus for sorting reusable raw-material pieces (5) which are moved continually in conveying direction (2) by a transport means (1), where the chemical composition of the raw-material pieces (5) is analyzed by laser-induced breakdown spectroscopy (LIBS) and automated sorting of the raw-material pieces (5) is implemented depending on the composition found, where the raw-material pieces (5) in a first step are subjected to a plurality of first laser pulses (6) in order to remove surface coatings and/or contaminants from the raw-material pieces (5), and in a second step, one or more second laser pulses (7) are directed at those locations of the raw-material pieces (5) from which the surface coatings and/or contaminants have been removed, with exposed material of the raw-material pieces (5) being converted by the second laser pulses (7) into a plasma, where the laser (3) used for the first and second laser pulses (6, 7) is the same, and the area of the raw-material pieces (5) over which the first laser pulses (6) are moved and which is freed from surface coatings and/or contaminants is greater than the area of the raw-material pieces (5) that is embraced by the second laser pulses (7), the focal diameter and the focal point of the laser beam being kept constant between the first and second laser pulses (6, 7). In this way it is possible, utilizing only one laser, to achieve undistorted analysis of the composition of the raw-material pieces (5) and to perform sorting in dependence on said analysis.
