Automatic Iron Removers Boost New Energy Industry Upgrade, Weak Magnetic Impurity Removal Rate Increased by 60%

2025-11-21

With the rapid development of the new energy industry, key raw materials such as lithium battery cathode and anode materials have put forward higher requirements for iron impurity control. An automatic iron remover developed for the new energy field has recently been applied on a large scale. Its original weak magnetic separation technology can effectively remove weakly magnetic substances such as iron oxide and stainless steel chips from raw materials, with a removal rate 60% higher than that of traditional equipment, building a solid line of defense for the quality of new energy products.

Weakly magnetic impurities in new energy raw materials easily lead to battery performance degradation, which is difficult for traditional equipment to remove accurately. The new automatic iron remover has increased the magnetic field strength to more than 1.5T through optimized magnetic field design, and combined with the modular magnetic rod array layout, it realizes efficient capture of weakly magnetic impurities of different particle sizes. The metal detection module integrated in the equipment can realize the linkage control of impurity monitoring and removal, and feed back iron removal data in real time to ensure the traceability of the production process.

After a lithium battery enterprise applied this equipment, the iron impurity content of the cathode material decreased from 0.005% to 0.0008%, the battery cycle life increased by 15%, and the production line failure rate decreased by 30%. "The fully automatic operation of the equipment not only reduces manual intervention but also makes the raw material purity stable and controllable, providing important support for us to overcome the high energy density battery technology," said the production director of the enterprise. At present, the equipment has served many leading new energy enterprises and has become a core equipment in the refining process of battery raw materials.
