Renewed Trust, New Journey Together | Liming Heavy Industry LM Vertical Roller Mill Empowers a Leading Lithium Cathode Material Enterprise to Consolidate the Foundation of Lithium Extraction

In the production chain of phosphate cathode materials, the sulfuric acid process represents the dominant technical route for lithium extraction from spodumene. Its core process is as follows: after high-temperature phase transformation roasting, raw spodumene ore must be ground to 200 mesh, mixed with concentrated sulfuric acid in a specific ratio, and then sent to the acidification roasting stage. Within this complete process chain, the grinding section serves as a critical link connecting preceding and subsequent operations. The uniformity of powder particle size distribution and continuous operational stability directly govern the efficiency of acid leaching reactions and lithium recovery rate, thereby exerting a profound impact on the grade of final lithium carbonate products.

The process adaptability and long-term operational stability of grinding equipment constitute a strategic pillar for the entire production line. Against the backdrop of expanding markets for power batteries and energy storage batteries, high quality, large scale powder preparation solutions with low maintenance costs provide vital support for upstream lithium enterprises to break through industrial bottlenecks.

The newly launched 30,000 TPA expansion project for battery-grade lithium carbonate uses spodumene as raw material and adopts a complete process route comprising phase transformation roasting, precision grinding, acid leaching, solution purification, evaporation concentration, and lithium precipitation & refining. The high quality battery grade lithium carbonate produced by the project will be directly supplied for the production of phosphate cathode materials, with end applications widely covering power batteries and energy storage batteries. Benefiting from the outstanding stability and process adaptability demonstrated by Liming Heavy Industry’s LM Vertical Roller Mill during Phase I cooperation, the client once again selected Liming Heavy Industry as its core equipment partner for this expansion project to jointly advance the high quality implementation of the project.

From process validation in Phase I to large-scale expansion in Phase II, the value empowerment of Liming Heavy Industry runs through the entire project lifecycle. Beyond supplying high-performance grinding equipment, it delivers tailor-made powder preparation solutions precisely adapted for lithium extraction production lines, with full-lifecycle services covering scheme design, installation & commissioning, and production operation.

Liming Heavy Industry LM Vertical Roller Mill leverages stable powder quality as its cornerstone to fully empower efficiency gains and quality upgrades for downstream lithium extraction. It helps enterprises boost self-sufficiency in battery-grade lithium carbonate, effectively unclog bottlenecks in upstream raw material supply, hedge against cyclical price volatility of bulk commodities, build sustainable cost advantages, and strengthen the resilience of independent control over the industrial chain.

Targeting the characteristics of roasted spodumene, including high hardness, strong abrasiveness and fluctuating moisture content, Liming Heavy Industry has developed a specialized complete grinding solution for new energy raw and auxiliary materials. Centered on the LM Vertical Roller Mill, this solution optimizes the main machine structure and adopts an innovative feeding and material distribution system to guarantee the operational stability and process adaptability of the whole powder production line from the source.

The solution meets the large-scale intelligent powder preparation demands for new energy raw and auxiliary materials such as spodumene, lepidolite and high-grade nickel matte, offering reliable assurance for high-quality production of lithium battery materials. Verified by multiple projects, its maturity and engineering implementation capability have won wide recognition from industrial clients.

High quality development of the lithium battery industry relies on the iterative upgrading of upstream core equipment and process technologies. The two collaborations between Liming Heavy Industry and the leading phosphate cathode material producer reflect high recognition of our technical strength, product stability and service capacity. Going forward, Liming Heavy Industry will continue to deepen its presence in the segmented field of new lithium battery materials, optimize green and intelligent powder preparation technologies, and leverage robust equipment capabilities to boost quality, efficiency and sound development across the lithium battery industrial chain.
