Study on the Application of HUICHUAN Eddy Current Separator ECS Series with Radial Multi-Layer Magnetic Structure Roller in Recovering Non-Ferrous Metals from Multi-Source Waste

Study on the Application of HUICHUAN Eddy Current Separator ECS Series with Radial Multi-Layer Magnetic Structure Roller in Recovering Non-Ferrous Metals from Multi-Source Waste

Aiming at the challenge of efficiently separating non-ferrous metals (copper, aluminum, silver, etc.) from electronic waste, household appliance waste, and end-of-life vehicle waste, this study systematically verified the performance of HUICHUAN Eddy Current Separator ECS series, featuring a radial multi-layer magnetic structure roller (high-frequency 32-pole + eccentric design + double-layer magnetic system), in the "screening classification-eddy current separation" collaborative process. The 20kg mixed samples provided by Japan Environmental Recycling Co., Ltd. were used for experiments. Results showed that the radial multi-layer magnetic structure increased the radial repulsion distances of aluminum, copper, and silver by 20.30%, 9.04%, and 7.46% respectively, with the radial repulsion distance difference between copper and aluminum increased by 132.42% and the eddy current force fluctuation coefficient reduced by 88.43%. Combined with screening pretreatment, the copper recovery rate from electronic waste reached 96.8% (purity 90.2%), aluminum recovery rate 95.5% (purity 89.1%); the aluminum purity from household appliance waste increased to 89.7%, and the separation efficiency of copper and silver from vehicle waste improved by 22%. This study confirms that the radial multi-layer magnetic structure breaks the bottleneck of traditional magnetic rollers with "low separation efficiency among different non-ferrous metals" by enhancing magnetic field gradient and stability, providing technical support for one-stop recovery of high-value metals from multi-source waste.

🔥《BREAKING! HUICHUAN’s "Waste-to-Treasure" End-of-Life Vehicle Line Launches in Serbia 》

The end-of-life vehicle (ELV) dismantling plant operated by HUICHUAN Technology in Serbia achieves the "turning waste into treasure" of ELVs through the full-chain technology of "crushing-conveying-sorting", with a processing capacity of 7-8 tons per hour. Its core technologies include:​ Dual-shaft shear crushing: High-strength alloy cutters handle hard materials such as vehicle frames and engines, while intelligent overload protection ensures continuous operation;​ Hybrid conveying system: Chain conveyors handle heavy metals, and belt conveyors manage lightweight plastics to prevent blockages;​ Precise Automotive Shredder Residue (ASR) sorting: Integrating inductive metal detection + permanent magnetic separation + eddy current separation + air separation, it recovers 98% of steel, 95% of non-ferrous metals, and 90% of plastics from ASR, solving the traditional challenges in ASR treatment.​ The project not only addresses the environmental issue of ELV accumulation in Serbia but also drives the local "green economy" through resource recycling, becoming a circular economy benchmark under the global carbon peaking goal.
