The client was working with petroleum coke, a key precursor material for advanced battery anodes. Their existing milling setup was inconsistent, struggling to reliably produce the ultra-fine, tightly distributed coke powder. They needed a solution that was not only precise but also scalable for their pilot production line.
The Epic Powder Solution
After reviewing their material properties and goals, our technical team recommended a tailored Fluidized Bed Jet Mill system. Our jet mill’s classification-first principle ensures only particles that meet the target size exit the chamber, guaranteeing exceptional uniformity. For this sensitive carbon material, the completely contact-free, wear-resistant design was also critical to prevent contamination and preserve the coke’s essential properties.
The system consistently milled the petroleum coke to a D70 of 5µm, providing the fine, uniform powder foundation the client’s battery chemistry required. It delivered a stable output of 50 kg/h, perfectly matching the throughput needed for their pilot-scale electrode material production. The client reported a marked improvement in the processability of their powder downstream and greater confidence in the quality of their experimental anode batches. The reliable data from our mill helped them streamline their R&D to production transition.
By providing a reliable tool for precise particle size control, Epic Powder helped this developer achieve a tangible, high-quality material. Their success in creating better-performing battery components starts with the fundamentals of powder technology—fundamentals we are built to master.
