Abstract
The minimum fluidization velocity was measured for various binary particle mixtures of coarse particles of group A or B and fine particles including group C particles of Geldart classification in the range where the weight fraction of the fine particles was less than 15 wt%. The minimum fluidization velocity decreased with the increase in the fraction of the fine particles in all cases; especially in the systems with group C particles, a remarkable decrease in the minimum fluidization velocity was observed with the increase in the fine particle fraction. Such a decrease in the minimum fluidization velocity observed in the systems with group C particles was expressed by the formation of aggregated particles consisted of the coarse and the fine particles. Mixing/segregation appearance of the system was also observed, revealing that group C particles can be fluidized and mixed homogeneously with coarse particles in a certain rage of the fine particle fraction. The range of the fine particle fraction for homogeneous mixing was dependent on the systems.
