| Abstract Scope |
The bulk density of petroleum coke used for anode manufacture is important to aluminum smelters as it generally relates to anode baked density. Coke bulk density has been extensively studied, including previous work by BP, that showed how particle shape is modified by different crushers, and that changes in shape influenced coke bulk density. Variation in Vibrated Bulk Density (VBD) was of similar magnitude as porosity, and that VBD for blends of shaft and non-shaft calcined cokes could be improved by jaw crushing the shaft coke in the blend. However, Carbon Plant coarse aggregate contains much larger particles than in these studies and occupy a significant volume percentage of an anode. A laboratory study was conducted to see if similar relationships between crushing technique, shape, and bulk density exists for larger particles with the goal of understanding if anode bake density can be increased through selective crushing of large particles. |
