A leading Korean supplier of lithium battery cathode materials faced severe agglomeration and non-uniform particle size distribution after high-temperature sintering. To improve the electrochemical performance of the final product, the customer required a reliable solution. The lithium battery cathode material De-agglomeration solution needed to achieve efficient de-agglomeration while strictly controlling metal contamination.
At the same time, the original particle morphology had to be preserved.
Core Solution: Epic Powder Pin Mill for Lithium Battery Cathode Material De-agglomeration
To meet the high hardness and high-purity requirements of cathode materials, we configured a dedicated Pin Mill system. We also delivered a complete turnkey solution covering the entire project scope.
- Precision Process Definition:
Simulated trials were carried out at our testing center. By optimizing rotor speed and airflow, sintered agglomerates were precisely “disassembled.”
This approach avoided indiscriminate grinding and unnecessary particle damage. - Comprehensive Engineering Design:
A complete engineering solution was provided. This included plant layout planning, automation workflow design, and civil engineering recommendations. - Non-standard Customization:
The Korean customer required extremely strict purity control. Therefore, all material-contact parts were protected with ceramic linings (alumina / silicon carbide). This design ensured zero additional metal contamination during processing.
Consulting and Technical Service Highlights
- Preliminary Feasibility Evaluation:
Sample testing was conducted at our test facility to compare de-agglomeration performance under different operating frequencies (D50 / Dmax), ensuring full compliance with the customer’s technical specifications. - On-site Technical Support:
Experienced engineers were dispatched to the project site in Korea to oversee installation guidance, system commissioning, and trial operation. - Automation Integration:
Seamless integration with the customer’s existing production line was achieved, enabling fully automated transfer from upstream sintering discharge to downstream packaging.
Project Results
- Product Quality:
The de-agglomerated material exhibited a narrow particle size distribution with no over-grinding, effectively preserving the original morphology of single-crystal or polycrystalline particles. - Efficiency Improvement:
The introduction of automation significantly reduced labor costs and enhanced production continuity. - Professional Delivery:
With comprehensive project schedule management and budget control, the system was successfully commissioned and put into operation on time.
