Elutriation from fluidized beds

Abstract Elutriation characteristics of widely different solids (density from 920 to 5900 kg/m 3 ) were measured in fluidized beds (up to 0.9 m in size) having high freeboard (7.5 m), using gas velocities up to 4 m/s. The experimental findings were compared with previously reported results and all the variables were well correlated with a simple empirical expression
