Ultrafine Jet Milling Solution for Apricot Shell Carbon (D50: 4–6 µm)

Project Background & Technical Challenges

Our client, a leading biomass activated carbon manufacturer based in Turkey, sought an efficient ultra-fine micronization solution for high-grade carbono de casca de damasco. Apricot shell carbon is renowned for its high hardness, dense micro-porous structure, and exceptional adsorption performance. However, downsizing abrasive hard carbon down to a strict micro-powder standard (D50: 4–6 µm) presents severe industrial processing challenges:

First, conventional mechanical impact mills suffer extreme blade and liner wear due to the high abrasive nature of hard carbon. Secondly, excessive heat generated during traditional grinding can destroy delicate micropores, compromising the material’s specific surface area (BET). Third, inconsistent particle sizing causes pore clogging in high-end slurry filtration and liquid coating applications.

The EPIC Fluidized Bed Jet Milling Solution

To resolve these pain points, Pó ÉPICO engineered a customized Fluidized Bed Air Jet Mill System equipped with a high-precision vertical turbine classifier.

Unlike mechanical grinders, air jet milling utilizes ultra-high-velocity compressed air streams to force carbon particles into self-impact collisions. This completely eliminates tool wear contamination and high thermal generation during milling. By optimizing the nozzle layout and classifier wheel RPM, our engineering team achieved sharp top-size cut control while keeping the internal pore matrix intact.
