This case study presents a detailed account of a real-world grinding mill installation project by LIMING, including project background, equipment selection rationale, installation process, commissioning results, and ongoing operational performance. The information is based on actual project data and customer feedback, providing valuable reference for similar projects.
Project Overview
A graphite processor in Heilongjiang, China, needed an ultrafine grinding line to produce 1250 mesh natural graphite powder for lithium-ion battery anode material and high-performance lubricants.
Specialized Equipment
The HGM100L ultrafine mill was configured with specialized graphite-grade components. Graphite's lubricity and softness (1-2 Mohs) require unique roller pressure settings to prevent over-compression. The air classification system was tuned for graphite's low bulk density and flake morphology.
Quality Achieved
The mill produced 3 t/h at 1250 mesh graphite powder with 95% crystallinity retention. The D50 particle size was 8 microns. Battery anode testing showed initial coulombic efficiency of 89%, meeting commercial battery material specifications. The gentle grinding preserved graphite's crystalline flake structure, which is essential for electrical conductivity and battery performance.
Project Insights & Lessons Learned
