Deep Dive into Rare Earth Recycling: Zenith European Mill Enables NdFeB Waste Regeneration

The successful implementation and stable commissioning of the large-scale NdFeB waste milling project in Vietnam serves as a benchmark case of Zenith’s services for the global rare earth solid waste resource utilization sector. As a global supplier of powder processing equipment and solid waste recycling solutions, Shanghai Zenith has been deeply engaged in rare earth solid waste regeneration for many years. Focusing on the core pain points of NdFeB waste powder production, we leverage mature powder grinding technology and extensive experience in global project delivery to develop customized high-efficiency milling solutions tailored for the rare earth industry.

Rare earths are indispensable strategic core resources for new energy, high-end manufacturing and new material industries, undertaking the vital mission of global low-carbon transition and high-end industrial upgrading. Among various types of recycled rare earth resources, wastes such as NdFeB production scraps and spent permanent magnets feature abundant reserves, high rare earth grade and remarkable recovery value. They serve as high-quality recycled raw materials to supplement primary rare earth resources and improve the closed loop of the rare earth industrial chain.

Targeting the local working conditions in Vietnam including high hardness of NdFeB waste, strict requirements for powder fineness and great difficulties in continuous mass production, Zenith custom-designed a complete intelligent milling production line for the customer, with the MTW European Trapezium Grinding Mill as core equipment. Optimized and upgraded specially for grinding industrial solid waste and high-hardness materials, this equipment can stably produce standard uniform powder of 350 mesh. It delivers precisely controllable powder fineness and even particle size distribution, perfectly matching the full-process technologies of rare earth hydrometallurgy, leaching-extraction and fine purification. It thoroughly solves the problem of unqualified powder from traditional equipment which cannot connect with downstream deep processing procedures, enabling waste NdFeB materials to be truly converted into high-value recycled raw materials.

Zenith MTW European Trapezium Grinding Mill is equipped with an intelligent control system. Featuring easy operation and high automation, it enables unattended operation and precise powder control. The optimized and upgraded complete machine structure adapts to high-intensity and long-duration continuous operation with stable performance and low failure rates. It is well suited for various plant working conditions and complex production environments, significantly reducing downtime losses. Meanwhile, the machine is fitted with closed-loop dust collection and energy-saving noise reduction systems, greatly improving energy utilization efficiency. Balancing high-efficiency production with environmental protection, it aligns with the trend of low-carbon and compliant development in the rare earth industry.

From preliminary survey and planning to post-project operation, maintenance and upgrading, Zenith has built a full-process one-stop service system for project implementation. During project execution, dedicated personnel follow up throughout equipment installation, commissioning, technical coordination and hands-on operator training. This quickly activates the production chain, greatly shortens the commissioning cycle and helps customers achieve mass production and profits rapidly.

After the project goes into operation, Zenith delivers long-term services including regular operation inspection, equipment maintenance, rapid fault response and process iteration & upgrading. We continuously optimize production processes to cut corporate maintenance costs and production energy consumption, ensuring the production line runs steadily at full load over the long term, so customers can operate production without worries and manage their business with peace of mind.

With reliable equipment performance, mature process solutions and a comprehensive service system, Zenith has earned extensive positive reputation in the global rare earth solid waste resource utilization sector. Our implemented projects span home and overseas markets, continuously supporting enterprises in transforming from inefficient and extensive processing to high-efficiency refined resource recovery.

Looking ahead, Zenith will deliver more professional customized solutions, superior equipment products and improved full life-cycle services to facilitate efficient recycling of rare earth solid waste worldwide, and empower the green, low carbon and high quality sustainable development of the rare earth industry.
