20,000 TPA Battery-Grade Lithium Carbonate Production Line! Liming Heavy Industry LM Vertical Roller Mill Leads a New Era for the Lithium Industry

Amid the rapid development of global energy storage and solid-state battery technologies, lithium resources have become core strategic raw materials underpinning the growth of the new energy industry, widely adopted in diverse fields including new energy vehicles and energy storage systems. As the lithium battery sector keeps expanding production capacity and upgrading technologies, demand for deep processing of raw materials such as spodumene and lepidolite continues to surge. The implementation of high-efficiency lithium extraction processes relies heavily on the technical support of core grinding equipment.

Sulfate Roasting Process

The sulfate method is currently the most prevalent technique for lithium extraction from lepidolite. Using sulfate as a roasting additive, the raw material undergoes high-temperature roasting and converts into soluble lithium sulfate, which is then leached to extract lithium.

With in-depth insights into lithium battery material processing technologies, Liming Heavy Industry has developed complete grinding processes for auxiliary raw materials in the new energy industry. The solution caters to large-scale intelligent powder production of new energy raw materials including spodumene, lepidolite and high-grade matte nickel, delivering reliable assurance for the high-quality manufacturing of lithium battery materials.

Liming Heavy Industry has entered a cooperation with Ganfeng Lithium, a leading lithium battery enterprise, to supply core grinding equipment for the Phase I Lithium Resource Comprehensive Utilization Project in Xianghuang Banner, Inner Mongolia. The project can process nearly 400,000 tons of lepidolite concentrate annually. Tailored perfectly to the processing characteristics of materials, Liming’s LM Vertical Roller Mill delivers robust technical strength and reliable performance, helping the enterprise hit its production target of 20,000 tons of battery-grade lithium carbonate per year and fuel the high-quality development of the lithium battery industry.

Adhering to the standard of "High-Quality Projects", Liming Heavy Industry’s team provides full-cycle follow-up services covering equipment installation, commissioning and operation. Services range from foundation positioning and process parameter calibration to on-site operation training and after-sales operation & maintenance support. Every procedure is precisely controlled to guarantee stable equipment operation and qualified finished powder quality, laying a solid foundation for the project to reach full production capacity and boost efficiency. This cooperation demonstrates the powerful synergy between upstream equipment manufacturers and core lithium material producers along the industrial chain.

Efficient conversion of lithium resources cannot be achieved without the technical support of high-performance equipment. Liming Heavy Industry LM Series Vertical Roller Mill integrates drying, grinding, powder classification and conveying into one unit. Adopting state-of-the-art grinding technology, it boasts remarkable advantages including high grinding efficiency, strong drying capacity, easy adjustment of finished product fineness and low operating costs. Its key technical and economic indicators have reached advanced international standards.
