This global supplier of battery materials was on a quest for a high-performance mulino a getto production line to process cobalt oxide (Co3O4). Cobalt oxide is a critical precursor material in the manufacturing of Lithium-ion battery cathodes. Its performance is heavily dependent on a finely controlled, consistent, and ultra-fine particle size. This is to ensure optimal electrochemical properties and energy density. Achieving this demanding fineness (D99 < 6µm) at a commercial production scale presented a significant challenge. Conventional milling methods often struggled with contamination, insufficient energy, or broad particle size distribution. These aspects leading to batch inconsistency and potential compromises in the final battery’s performance and safety.
After a thorough technical evaluation, the company selected Polvere epica as their strategic technology partner. We designed and installed a tailor-made MQW40 jet milling system, specifically engineered for the precise and efficient grinding of high-value, hard-to-process materials like cobalt oxide. Our solution leveraged advanced mulino a getto a letto fluido technology, utilizing high-velocity air to achieve particle-on-particle impact grinding. This method ensured minimal contamination, precise control, and effective de-agglomeration, all while maintaining the material’s critical chemical purity.
The system provided exceptional control over the particle top-cut size, consistently achieving the stringent target of D99: 5.8µm. Furthermore, the robust design and optimized grinding chamber of the MQW35-40 enabled a stable and high output of 700 kg/h. This remarkable combination of precision and massive throughput directly translated into a superior product quality for the client’s battery customers and a strong competitive advantage in the market.
Today, empowered by Epic Powder’s reliable and high-capacity jet pulverizer, the company has solidified its position as a leading supplier of premium-grade cathode precursors for the global battery market. This successful collaboration has cemented a long-term strategic partnership, paving the way for future projects and continuous innovation together.
