Battery & EV Materials

Battery manufacturing needs particle-size control without metallic contamination. Our systems micronize graphite anode, silicon anode and cathode precursor powders to the fineness electrode coating demands.

Industry profile — Battery & EV materials

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.

01 / Applications

Typical battery & EV material applications

Four material streams across battery manufacturing — each with its own purity and fineness target.

01
Graphite photo

Graphite Anode Micronization

Autogenous fluid-energy grinding reduces graphite to sub-micron D50 with no metallic pickup from grinding media.

02
Silicon photo

Silicon Anode Materials

Ceramic-lined, media-free jet milling protects silicon anode powders from contamination during ultra-fine reduction.

03
Cathode photo

Cathode Precursor Grinding

Hard, dense precursor powders reduced via cascading and cataracting ball-mill action.

04
Feedstock photo

Electrode Feedstock Pre-sizing

Bulk precursor material pre-sized by hammer mill before fine grinding or classification.

02 / Advantages

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.
