At the highly influential China International Aluminium Industry Fair spanning the global aluminium industrial chain, the green transition of the recycled aluminium sector stood out as a core theme. As a leading enterprise in sorting equipment, Longi made a prominent appearance, showcasing its intelligent sorting line technology for aluminium scrap and a full range of sorting equipment for renewable resources.
On the opening day, its booth drew constant crowds, attracting numerous industry professionals to stop for visits. Faced with a steady stream of clients and partners, the technical team of Longi delivered tailored Longi solutions with professional expertise and solid operational performance data. Non-stop on-site inquiries and vigorous business discussions not only demonstrated the outstanding performance of the equipment, but also reflected Longi’s profound technical expertise and comprehensive layout in the recycling and utilization of renewable resources through in-depth exchanges of detailed technical proposals.
With the in-depth advancement of the dual carbon goals, scrap aluminium feedstock has grown increasingly complex in composition. Balancing high recovery rate and high purity has become a universal challenge plaguing numerous processing manufacturers. Targeting this industry bottleneck, the intelligent aluminium scrap sorting line unveiled by Longi is engineered for efficient purification of recycled aluminium materials. It features an integrated innovative process combining dry pre-sorting and multi-stage precision sorting to effectively resolve longstanding industry pain points:
Full-dimensional collaborative sorting
A multi-stage stepped collaborative sorting system consisting of magnetic separators, trommel screens, eddy current separators and X-ray metal sorters enables systematic and high-efficiency separation of ferrous contaminants, bulk non-metallic impurities, non-ferrous metal contaminants and fine non-metallic particles from recycled aluminium scrap.
Intelligent operation and control
The entire production line runs fully automatically via a PLC intelligent control system with zero manual intervention. It guarantees precise impurity removal and purification while drastically boosting production stability and output consistency.
Outstanding performance metrics
The line delivers a processing capacity of 10 to 40 tons per hour, with an overall non-ferrous metal recovery rate exceeding 99%, providing recycled aluminium producers with a stable, efficient and high-purity purification solution.
Eco-friendly and low-carbon process
The entire workflow adopts dry physical sorting technology, generating no wastewater or pollution while delivering remarkable energy savings, striking a balance between green manufacturing and cost management.
High-purity aluminium sorted by this production line meets premium manufacturing standards and can be directly supplied to sectors including aerospace and new energy vehicles. This technology not only realizes high-value utilization of waste materials, but also accelerates the transformation of the recycled aluminium industry from extensive recovery to refined intelligent manufacturing.
