Abstract Quantitative method is used to experimentally measure the minimum spouting velocity in shallow conical spouted bed. And a new minimum spouting correlation for shallow conical spouted beds is developed. It is based on spherical ZrO 2 particles whose density is as high as 5890 kg/m 3 while the other U ms correlations published so far are mainly based on relatively deep conical beds composed of lower density particles with density around or lower than 3000 kg/m 3 . The new U ms correlation can predict U ms of heavy particles well within the range of the experimental matrix. © 2011 Canadian Society for Chemical Engineering
