The client was engaged in petroleum coke milling, processing a key precursor for advanced battery anodes. Their existing setup was inconsistent, struggling to reliably produce the ultra-fine, narrow-distribution powder required. They needed a scalable solution that could deliver precision for their pilot production line.
The Epic Powder Solution
Following a review of the client’s material specification and requirements, EPIC’s engineering team specified a Fluidized Bed Jet Mill system. The sınıflandırma-first operating principle — where a dynamic sınıflandırıcı controls the exit condition before particles leave the grinding zone . It ensures a consistently narrow particle size distribution without overgrinding. For petroleum coke, the fully contact-free design is non-negotiable: any media wear introduces conductive contaminants that compromise anode purity and first-cycle efficiency.
The configured system achieved D70 ≤ 5 µm at 60 kg/h under stable continuous operation, meeting the client’s pilot-scale electrode material production rate.
Particle size control at this level is a foundational requirement for battery anode development. EPIC Toz Makineleri provides the process reliability that makes petroleum coke milling achievable.
