The turnkey system technology offered by cleansort includes sophisticated and maintenance-free laser technology based on state-of-the-art diode-pumped solid-state lasers from cleanLASER. The complete technology for material conveyance and separation is included as well as the technology for recognition of the component geometry and sorting by means of powerful parallel air pulse technology.
The metallic old and new scrap can be fed from a bunker in almost any size class (from approx. 25 mm to 800 mm edge length). The conveying and separating technology then ensures transfer to the conveyor belt. Here the parts with a width of up to two meters are distributed evenly and as far as possible without overlap and accelerated to a transport speed of up to three meters per second.
In the further course, fast laser scanners measure the separated scrap pieces with regard to their geometry. This measurement is important to determine the center of mass for the subsequent sorting of the respective part.
Directly after the fast object detection, the laser processing with the cleansort module follows. The cleaning and measurement of the exact fingerprint, e.g. in the case of unpainted aluminum, takes place within only six milliseconds. The success rate of the measurement is over 93% despite this very short duration. This means that within the blink of an eye almost 30 LIBS measurements can be performed with the system. The components only cover a distance of about 20 mm for each decoating and measurement. The enormously short processing times thus enable the parallel processing of several parts lying next to each other or the removal of thicker layers of lacquer or other relevant coatings for the measurement.
Within the approximately seven-year development period of the technology, the system was thus brought to economic market maturity.
THE ADVANTAGES OF THE CLEANSORT SORTING TECHNOLOGY
HIGH PERFORMANCE PRE-ABLATION
The high performance pre-ablation allows reliable analysis of heavily contaminated or coated materials. Whether galvanized steels, scrap from waste incineration plants covered with a thick layer of soot and ash, or heavily rusted steels, all these materials can be reliably sorted thanks to high-performance pre-ablation.
MULTIVARIABLE MATERIAL ANALYSIS
Für Schrottverwerter ist der flexible Einsatz der Anlagentechnik von besonderem Interesse. Aufgrund des breiten Messspektrums lässt sich die Anlage, nach einer Freigabe und Kalibrierung, auf Knopfdruck von der Sortierung von Buntmetallen auf bspw. die Sortierung von Stahl umschalten und sowohl eine qualitative als auch eine quantitative Analyse ausführen.
The system can be freely configured: Starting with a conveyor belt width of 250 mm and only one measuring system up to a conveyor belt width of 2,000 mm and eight measuring systems, the plant can be adapted to the specific scrap.
HIGH THROUGHPUT THANKS TO SCANNING MEASURING SYSTEM
Thanks to the two-fraction sorting and the cascadable design of the system, high throughput rates can be achieved.
