Petroleum Coke Milling Roller Mill Project in Jiangxi

An energy materials company specializing in advanced battery anodes approached Epic Powder with a complex challenge. They needed a reliable and scalable solution for petroleum coke milling—processing this critical precursor material into an ultra-fine powder with exceptional consistency. Their existing system was plagued by inconsistent output and could not maintain precision as they scaled from lab trials to pilot production.

The Challenge

To meet the strict performance requirements of next-generation anodes, the client needed petroleum coke powder with a specific, narrow particle size distribution (PSD). Their current milling setup suffered from:

  1. Inconsistent Grinding: Frequent variations in fineness led to high material rejection rates.
  2. Scalability Issues: The existing equipment could not maintain precision at higher production volumes.
  3. Operational Inefficiency: High energy consumption and frequent wear-related downtime increased costs.

The Epic Powder Solution

Epic Powder engineers recommended our advanced Ring Roller Mill, configured specifically for the abrasive and high-purity demands of petroleum coke. The solution provided:

  • Precision Classification: An integrated high-efficiency classifier ensured a tightly controlled, ultra-fine product.
  • Stable & Scalable Performance: The grinding principle (centrifugal force between rolls and ring) delivered consistent results across varying feed rates.
  • Enhanced Durability: Wear-resistant components minimized contamination and extended maintenance intervals.

Additional Benefits:

The new ring roller mill can reduce power consumption per ton by 25% and achieve 99.5% reliability in meeting target PSD specifications. The client successfully validated their process at pilot scale and is now planning for full-scale production using Epic Powder’s technology.

This case demonstrates that selecting the right petroleum coke milling technology is crucial for battery material success. Epic Powder’s ring roller mill provided not just a machine, but a scalable, efficient, and precise solution that turned a production bottleneck into a competitive advantage.
