Presentation Title Influence of Crusher Type and Particle Shape on the Bulk Density of Blended Shaft and Hearth Calcined Anode Grade Petroleum Coke
Author(s) Howard Childs, Barry Sadler, Mike Davidson
On-Site Speaker (Planned) Howard Childs
Abstract Scope The bulk density of anode grade petroleum coke is an important property for aluminum smelting and has been extensively studied. This includes previous work by BP showing that particle shape was modified by different crushing technologies, and that changes in shape (i.e. sphericity and convexity) influenced coke bulk density. These laboratory studies indicated that the impact of particle shape on the Vibrated Bulk Density (VBD) of a range of cokes and butts was of similar magnitude to that of porosity. In ongoing Customer support efforts, this work has been extended to study whether modifying particle shape can improve the VBD of blends of cokes calcined using different technologies – shaft and rotary hearth kilns. The results of this study are presented and the potential to enhance the VBD of shaft/non-shaft calcined coke blends by modifying particle shape with different crusher types determined at a laboratory scale.
