Step 1: Raw Green Coke Screening & Classification
Refined screening removes impurities, dividing green coke into low-sulfur and medium-sulfur materials to separate production lines for targeted calcination.
Step 2: Rotary Kiln High-Temperature Calcination
Qualified raw coke is heated at 1200–1350℃ to fully remove moisture and volatile matter, optimizing carbon crystal structure and electrical conductivity.
Step 3: Cooling, Crushing and Multi-Layer Sieving
Hot calcined coke is cooled, crushed and screened into various particle sizes according to global customer customized requirements.
Step 4: Full Batch Lab Inspection & Export Packaging
Each batch undergoes sulfur, ash, density and granularity testing; qualified products are packed with moisture-proof jumbo bags for sea transportation.
Core Industrial Applications
Product Advantages
Stable ultra-low sulfur control
Raw material source strictly limited to low-sulfur oil, batch sulfur fluctuation is minimal for long-term continuous production.
Low ash & high fixed carbon
Less impurities after calcination, effectively improving the finished carbon material electrochemical and conductive performance.
Fully customizable granularity
We produce lumps, medium particles and ultrafine powder to match different calcination equipment and grinding processes.
Steady bulk supply & complete test certificates
Long-term stable refinery cooperation ensures sufficient stock; complete COA test reports attached for every shipment.
