A leading South Korean materials company specializing in energy storage and environmental purification sought to improve the performance of its porous carbon products. The goal was to achieve ultrafine, uniform particle size while maintaining the material’s internal pore structure, which is essential for high adsorption capacity and excellent conductivity. Traditional mechanical grinding methods caused excessive heat and pore collapse, reducing product performance.
Challenges
- Maintaining the delicate pore structure of porous carbon during grinding.
- Achieving a narrow particle size distribution below 5 μm.
- Avoiding contamination and oxidation caused by high temperatures.
Epic Powder Solution
Epic Powder provided a customized jet mill system designed specifically for porous carbon ultrafine grinding. The system uses high-speed airflow to achieve collision-based particle reduction without mechanical contact, minimizing heat generation and contamination.
Key technical features include:
- Low-temperature milling to preserve pore integrity.
- Precise air classification for narrow particle size control.
- Closed-loop system ensuring stable and clean production.
Results
After installation and commissioning, the Korean client successfully achieved:
- Average particle size D50 < 3 μm, with uniform distribution.
- Over 95% pore structure retention.
- Improved adsorption efficiency by 20%.
- Output: 500kg/h
