Abstract:
This investigation focused on the effect of the operating parameters, barite content and particle size on the minimum fluidization velocity and particle agglomerate sizes of select LiF-barite binary mixtures. Experimental results showed that the relative fluidization in the bed of a binary mixture was better than the fluidization of a single component LiF bed. Results also identified two distinct regions in binary mixtures; namely the fragmentation and lubrication regions. In addition, it was found that the Zhou-Li model could be used to predict particle agglomerate sizes by explaining the forces present between agglomerate particles. The calculated results for the binary system agreed well with experimental data.
