Waste batteries contain abundant copper and aluminum resources, however, how to effectively separate these valuable materials in the process is a technical challenge. Traditional sorting devices can often only perform a rough sorting, resulting in the purity of the material is not ideal.
In order to solve this problem, the present invention proposes an innovative copper-aluminum sorting system and aluminum grain deep processing system. This system adopts the ingenious combination of multi-stage sorting equipment and pulverizer, aiming to improve the separation effect of aluminum particles and copper particles in the material, reduce the copper content in the subsequent aluminum particles, and further improve the purity of the material.
The primary sorting mechanism is the core component of the system, which precisely separates the copper and aluminum particles in the crushed material. The sorted copper particles are directly lifted to the bagging machine through the material conveying mechanism to achieve rapid utilization. The separated aluminum pellets are fed into the pulverizer for further grinding and granulation.
Inside the mill, the unique design of the grinding roller mechanism and the feeding mechanism makes the aluminum particles more uniform and delicate in the grinding process. At the same time, through the combination of the screening mechanism and the return material pumping mechanism, black powder, coarse aluminum particles and fine aluminum particles can be further separated. The black powder is directly **, and the coarse aluminum particles are returned to the mill for grinding and granulation again in order to form fine aluminum grains.
The fine aluminum particles of grinding and granulation are sorted again through the secondary sorting mechanism, and the aluminum particles and copper particles in the ground materials are completely separated. The combination of this multi-stage sorting and grinding granulation not only improves the separation effect, but also ensures the purity of the first material.
In short, the copper and aluminum sorting system of lithium battery processing equipment and its aluminum particle deep processing system have effectively solved the problem of separation of copper and aluminum materials in waste batteries through innovative design and technical means, improved the purity of the first material, and contributed to the recycling of resources.
