Battery Material Milling and Classification
Cathode powders, graphite anodes and solid-electrolyte precursors need different processing routes. For LFP and other cathode materials, the starting points are particle-size distribution and contamination limits. Graphite may also need shaping. We select the milling, classification and collection stages around your material, then use sample results to assess the production configuration.
- Control the target particle-size distribution and coarse-particle limit.
- Choose contact materials and ceramic lining to suit the impurity specification.
- Verify sample results, collection and continuous operation before scale-up.

These routes are starting points. The final configuration depends on material data and trial results.

Do all battery materials need ceramic lining?
No. The decision depends on the allowed impurities, material hardness, wear and required throughput. We review the contact surfaces against your specification and compare feed and finished-powder test results.
Do cathode and graphite-anode powders use the same equipment?
Not usually. Cathode processing often focuses on particle-size distribution and contamination, while graphite may also require spheronization and control of the fine fraction. Each route needs its own trial criteria.
When should inert gas protection be considered?
Where oxygen or moisture sensitivity, dust characteristics or your process requirements call for it. Share the material safety data sheet and atmosphere limits so the protective configuration can be assessed.
Can a sample trial determine the production model?
A trial provides a basis for selection. Production sizing also needs checks on continuous throughput, collection, contact materials and site conditions. Send the feed size, target D50/D90/D97, capacity and impurity limits before testing.
