Under the wave of new energy, the demand for lithium resources has soared, and the large maintenance residues in the electrolytic aluminum industry are not only an environmental burden but also a "urban mine" hiding lithium resources. How to achieve harmless and resourceful disposal of these maintenance residues and efficiently extract industrial-grade lithium carbonate has become a key issue in the industry. Henan ZK, with its core products such as rotary kilns and ball mills, has constructed a full-process solution, transforming "waste" into "lithium treasures", and empowering the industry's green development.
The components of electrolytic aluminum maintenance residues are complex and their disposal is difficult. Traditional methods often cause secondary pollution. With the implementation of relevant policies, the resource recycling of maintenance residues has ushered in a golden opportunity, and the core of lithium extraction lies in the adaptability of equipment. ZK has been deeply ploughing this field for many years and has maximized the synergistic advantages of rotary kilns and ball mills， breaking through the conversion barriers.
The customized rotary kilns provided by ZK are the core calcining equipment. They optimize the structure and materials based on the characteristics of maintenance residues to avoid corrosion and deformation. Precise temperature control ensures a conversion rate of 96-98% for lithium elements， combined with energy-saving and smoke treatment systems， achieving "environmental protection + efficiency" dual compliance and solving industry pain points.
ZK provides "research and development - manufacturing - operation and maintenance" full-process services， linking the core equipment with the supporting systems， customizing exclusive production lines， and keeping equipment investment and operation costs lower than the industry average， helping customers achieve environmental protection and economic benefits.
As a key equipment manufacturing unit in the industry， ZK has participated in the construction of multiple lithium battery material production lines， and its equipment is widely used in various lithium extraction scenarios， earning global trust.
Under the "dual carbon" goal， ZK uses rotary kilns as the core to help enterprises solve the problem of maintenance residues， promoting the transformation of the electrolytic aluminum industry and the high-quality development of the new energy industry， and jointly building a new green industrial ecosystem.
