Turn Waste into Treasure! Liming Heavy Industry LM Vertical Mill Unlocks New Potential of NdFeB Scrap

NdFeB（neodymium-iron-boron）is a new magnetic functional material, known as the "King of Magnets". In the production and processing of NdFeB permanent magnet materials, a large amount of debris, leftover materials, as well as residual raw materials from the processes of compression molding and sintering are generated, which are generally referred to as NdFeB scrap in the industry. Recovering valuable elements such as rare earths and iron from NdFeB "scrap" has incomparable advantages over producing rare earth elements from ores. It features short production processes and low costs, complies with the national management policies on rare earth resources, and is conducive to environmental protection.

Precious products such as neodymium oxide, terbium oxide, dysprosium oxide and cobalt oxide can be obtained from NdFeB scrap. Industrial waste is recycled and reused, a process that imposes extremely strict requirements on the grinding precision, production capacity and environmental protection level of grinding equipment.

With outstanding performance, Liming Heavy Industry's grinding equipment can efficiently complete waste treatment. It serves as a key equipment support for the circular utilization of rare earth resources, responds to national industrial policies, and stands as a pioneering equipment to help enterprises achieve the value transformation of "turning waste into treasure".

During the Liming Heavy Industry After-Sales Tour of Grinding Mil, the visiting team went to the site of a large domestic NdFeB scrap recycling project. Since its commissioning, the production line has operated stably with output exceeding expectations. Behind this success are not only the high-quality grinding equipment and technology of Liming Heavy Industry, but also the comprehensive after-sales service support and professional maintenance team.

Processed Material: NdFeB Recycled Scrap

Fineness: 200 Mesh

Equipment: Liming Heavy Industry LM Vertical Roller Mill

This project adopts intelligent batching, multi-layer furnace sintering, and crushing by Liming Heavy Industry's LM Vertical Roller Mill system, ultimately producing mixed rare earth oxides. The entire production system is efficient, energy-saving, environmentally friendly, and features a high level of automation.

Liming Heavy Industry has always adhered to its service philosophy, committing to providing customers with a one-stop service experience of "peace of mind, reassurance, and confidence". During the return visit, the Liming Heavy Industry service team provided multi-dimensional professional services. They guided operators in mastering the usage skills of the intelligent control system, simplifying complex operations into convenient ones, and helping to quickly improve operation and maintenance capabilities.

NdFeB scrap is a valuable secondary source of rare earths, but the composition of scrap from different sources varies, imposing extremely high requirements on equipment during the grinding and preparation process. NdFeB powder with stable purity, a narrow particle size distribution range, and good fluidity is conducive to producing high-performance rare earth magnetic products.

Liming Heavy Industry's LM Vertical Roller Mill perfectly meets the requirements for NdFeB grinding. As a product with independent intellectual property rights developed by integrating modern grinding technology, the equipment integrates grinding, drying, powder separation, and conveying into one. It features high product purity, precise particle size control, energy conservation and consumption reduction, high intelligence, and 24/7 continuous and stable production, making it the preferred equipment for the industrial recycling of NdFeB scrap.

In the future, Liming Heavy Industry will continue to forge quality through technology and safeguard benefits with services. It will empower more new energy enterprises with "Liming Quality", contribute to China's green and low-carbon transition, and boost the upgrading of the new energy industry!
