THE PRODUCT

THE LIBSSORTR1200

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 of the process, fast laser scanners measure the individual scrap pieces with regard to their geometry. This measurement is important to determine the center of mass for the later sorting of the respective part. At the same time, it serves to determine a surface on the scrap part that is as flat as possible for decoating and LIBS measurement.

The intelligent software makes it possible to precisely determine the "landing point" of the laser.

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 99% despite this very short duration. This means that within the blink of an eye almost 20 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 five-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

The flexible application of the plant technology is of particular interest to scrap recyclers. Due to the wide measuring spectrum, the plant can be switched from the sorting of non-ferrous metals to the sorting of aluminium or steel at the push of a button and both qualitative and quantitative analysis can be carried out.

VARIABLE SEPARATION

The system can be freely configured: Starting with a conveyor belt width of 400 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.
