Advanced LIBS sorting: the future of metal recycling

SGM Magnetics and Cleansort have joined forces to bring the most advanced LIBS sorting technology to the global market.

The collaboration enhances metal recycling efficiency by combining expertise in separation technologies with cutting-edge laser-based analysis. SGM Magnetics is confident this innovative approach is the future.

Revolutionising metals sorting

Laser-Induced Breakdown Spectroscopy (LIBS) is a breakthrough technology that allows real-time elemental analysis of metallic scrap. LIBS uses a high-intensity laser to vaporise a small fraction of the material, generating a plasma with a spectral signature to reveal its exact composition.

This provides exceptional accuracy, enabling precise sorting of different metal alloys in a continuous flow process.

Key features & advantages are:

• Laser pre-treatment: conventional LIBS sorting is often hindered by contaminants on metal surfaces. Clean2Sort modules employ high-power laser ablation to remove coatings, oxidation and impurities before analysis, ensuring reliable measurement results.
• Ultra-fast processing: operating at up to three metres per second, the system can conduct multiple lasers passes, removing layers of paint or corrosion within milliseconds.
• High-precision alloy identification: LIBS technology enables the differentiation of metal alloys at a detailed level, including distinguishing aluminium series 5000 from 6000, and even identifying specific grades such as 6010 or 6016.
• Modular and scalable design: the system can be customised for processing requirements with conveyor widths ranging from 720mm to 1 440mm and throughput capacities of up to 11 tonnes per hour.

SGM Magnetics, known for its expertise in magnetic, eddy current, induction, X-ray, and ballistic separation technologies, adds LIBS sorting to its portfolio through its partnership with Cleansort. This provides customers with a comprehensive and integrated approach to metal recycling, ensuring the highest recovery rates and quality standards in the industry.
