Amid the booming new energy industry, global demand for lithium resources has surged. The massive volume of overhaul residues generated by the electrolytic aluminum industry, long regarded as an environmental burden, is actually an urban mine rich in latent lithium resources. Realizing the harmless disposal and resource utilization of overhaul residues, as well as the efficient extraction of industrial-grade lithium carbonate, has become a core proposition for the industry. Leveraging its core products — rotary kilns and ball mills — Zhengzhou Mining Machinery has developed a full-process solution that transforms waste residues into high-value lithium materials, empowering the green development of the industry.
Electrolytic aluminum overhaul residues feature complex components and high disposal difficulty, and traditional treatment methods are prone to secondary pollution. With the implementation of stringent environmental and industrial policies, the resource utilization of overhaul residues has ushered in promising development opportunities. The key to lithium extraction lies in professional and adaptive equipment. With years of in-depth industry experience, Zhengzhou Mining Machinery maximizes the synergistic advantages of rotary kilns and ball mills, breaking through technical barriers in lithium conversion from residues.
As the core calcination equipment, the customized rotary kiln developed by Zhengzhou Mining Machinery is optimized in structure and material to adapt to the characteristics of overhaul residues, effectively preventing equipment corrosion and deformation. Its precise temperature control system boosts the lithium element conversion rate to 96~98%. Equipped with energy-saving configurations and flue gas treatment systems, the equipment achieves dual standards of environmental compliance and high efficiency, solving core pain points plaguing the industry.
