Modelling the Solids Transport Phenomena Within Flighted Rotary Dryers Thesis submitted by Andrew LEE, BE(Hons) QLD in May 2008 for the degree of Doctor of Philosophy in the School of Engineering James Cook University
Highlights Flighted rotary dryer design loading is experimentally determined. The effect of rotational speeds and dynamic repose angles is described. Image analysis is used to quantify the saturation of the airborne solids at design conditions. CFD simulation is coupled with image analysis to quantify flight unloading. A geometric flight unloading model is presented to model design conditions.
Highlights Increase in flight length ratio can lead to bulk movement of solids. Most suitable discharge of the flight can be expected at l 2 /l 1 close to 1. The drum can be operated at less number of flights than the theoretical one. Recirculation of the entrained air disturbs the uniformity of the curtains. The model is usable to scale up of the flight design for industrial units.

Chapter 7 presents the validation of the solids transport model using experimental data from an industrial flighted rotary dryer. The geometric flight unloading model was integrated into the overall solids transport model for a rotary dryer, and experimental data from Invicta Sugar Mill's dryer number 2 was used to statistically determine the ...
Multiscale modelling of industrial flighted rotary dryers . By Olukayode Oludamilola Ajayi. ... However, most industrial rotary dryers are operated at under-loaded or overloaded, which results into poor efficiency of the dryer and the optimal economics of the dryer will not be achieved. As such, accurate estimation of the design load is ...
