Rotary dryers are widely used in industrial processes to dry particulate solids [1], [2], [3]. This kind of dryer is made of a rotating tube that can be slightly inclined to induce solid flow in the longitudinal direction. Wet granular material is usually injected into the dryer through a hot temperature air stream.

A mathematical model for the rotary dryer that determines the total residence time is developed. Experiments were performed in a laboratory-scale direct contact rotary dryer with the gas flowing concurrently with the solids. The model predictions depicted that the total residence time decreases with increasing the inclination of the rotary drum, the speed of …

ABOUT THE COURSE: Chemical process plants include a number of important equipment such as reactors, distillation columns, absorbers, heat exchangers, evaporators, crystallizers, etc. Design of such equipment should be carried out a priory to set-up a process plant and thus, it is basic step in a chemical process. Mechanical design of equipment addresses the stress and …
Dryer Design - Free download as PDF File (.pdf), Text File (.txt) or read online for free. This document discusses dryers and drying processes. It begins by introducing different types of dryers including batch and continuous dryers. It then describes the physical mechanisms of drying, including moisture transport mechanisms and key drying terms.
For evaporating moisture from concentrates or other products from plant operations, Rotary Dryers are designed and constructed for high efficiency and economy in fuel consumption. Whenever possible to apply heat direct to the material to be dried, Rotary Dryers of the Direct Heating Design are used. If it is not possible to apply heat direct to ...
