The modern scrap car shredding line

    The modern scrap car shredding line embodies advanced sorting concepts in the resource recycling field.

    After the entire vehicle undergoes intensive shredding pretreatment, the mixed materials first go through the magnetic separation process, where an overband magnetic roller efficiently separates ferrous scrap steel using its powerful magnetic force, creating fundamental conditions for subsequent sorting. Subsequently, the remaining non-magnetic materials enter the eddy current separation stage. This process utilizes the eddy current effect generated by an alternating magnetic field to accurately eject and separate non-ferrous metals with good conductivity, such as aluminum and copper, enabling the recovery and reuse of high-value metals. Finally, the materials after metal extraction proceed to the refined processing stage, where a combination of technologies including air separation, bounce screening, and near-infrared sorting finely separates different types of non-metallic materials, such as plastics and rubber, based on differences in material density, elasticity, and optical characteristics.

    The entire production line forms a comprehensive multi-stage sorting system through the "shredding-magnetic separation-eddy current separation-refined sorting" process route.

    This system not only significantly improves resource recovery rates and product purity but also provides reliable technical support for the development of the circular economy. It transforms scrap cars from an environmental burden into renewable urban mineral resources, reflecting the important direction of modern industrial sustainable development.
