The sizing and design of a rotary dryer is a complex process involving a number of factors and considerations. This presentation looks at the importance of custom rotary drum dryer design over a one-size-fits-all solution, and the many material characteristics and environmental factors that should be considered during the design process.
The factors affecting the modeling of a rotary dryer can be classified as follows (Kelly 1995): physical properties of the solids, such as particle size and shape, density and moisture content, dryer variables, such as the diameter and length of the drum and the design and number of lifting flights and
Direct-heat rotary dryers can operate on fuel oils, natural gas, propane or coal. In addition, steam-heated clean air and flue gases may be used as a heating medium. Indirect-heat rotary dryers are available in steam tube designs and standard rotary models. When the standard rotary design is used, convection heat transfer is employed.
