The History and Future Challenges of Calcined Petroleum Coke Production
Rotary hearth calciners result in less fines loss from the coke bed, resulting in a higher recovery of calcined coke per ton of GPC. This is an economic advantage when operating the calciner but leads to a product with a higher fines content (<0.5 mm), which is not always desirable for an anode paste plant. ...

Kiln vs flash calciner
Q: What factors should a customer consider when looking at kiln versus flash calciner technologies? What makes one more suitable than the other? TK: Both the rotary kiln approach and the suspension calciner effectively convert spodumene. The primary consideration of which approach is best is the concentrate particle size distribution (PSD).
