Abstract
Changes in particle size distribution play an important role in fluidized b ed processes, and these changes are dominated by elutriation and carryover of fines and by attrition or agglomeration. In this study on attrition in g as-fluidized beds, we found that the attrition is a function of the particl e size distribution, the jet velocities and the overall superficial gas vel ocity. Empirical equations have been developed to predict the attrition rat e.
