Fine powders Clean energy
Battery and EV material manufacturing depends on tightly controlled particle-size distributions and freedom from metallic contamination — a stray metal particle in an electrode coating can compromise cell performance and safety. Our systems reduce graphite, silicon and cathode precursor powders to their target fineness without introducing wear metal into the product stream.
From bulk precursor pre-sizing through sub-micron anode micronization, each stage is matched to the platform best suited for that material's hardness and purity requirement.
Typical battery & EV material applications
Four material streams across battery manufacturing — each with its own purity and fineness target.
Graphite Anode Micronization
Autogenous fluid-energy grinding reduces graphite to sub-micron D50 with no metallic pickup from grinding media.
Silicon Anode Materials
Ceramic-lined, media-free jet milling protects silicon anode powders from contamination during ultra-fine reduction.
Cathode Precursor Grinding
Hard, dense precursor powders reduced via cascading and cataracting ball-mill action.
Electrode Feedstock Pre-sizing
Bulk precursor material pre-sized by hammer mill before fine grinding or classification.
Key advantages
Built for the purity and precision battery-grade powders demand.
Zero metallic contamination
Jet-mill autogenous grinding and ceramic linings eliminate metallic pickup that would compromise electrode performance.
Sub-micron precision
D50 1–10 µm micronization for graphite and silicon anode powders.
Hard-material capability
Ball-mill tumbling handles dense, abrasive cathode precursor materials.
Isothermal, self-cooling grinding
Compressed-air expansion keeps heat-sensitive materials cool during fine grinding.
