Jun 16, 2010 · Abstract. The residence time in a pilot-scale rotary dryer was determined experimentally for four types of solids (fish meal, sand, soy meal, and sawdust) while varying the solids flow rate, the slope of the dryer, the speed of rotation, and the flow rate of gas with the objective to develop a correlation to predict the mean residence time for inclined and horizontal rotating dryers and to …

a study of particle motion in rotary dryer

Numerous equations have been proposed for residence time in rotary dryers (Kelly and O'Donnell, 1977). In many of these studies, only average holdups (H*) and solids feedrate were considered. The average residence time for the particles in these cases is given by . The holdup H* is usually determined by suddenly stopping the drum and
