This is understandable of the wide range of materials which can be dried in them and if they are correctly designed and operated high thermal efficiencies are obtained. They consist of long drum driven at low speed

    Figure 1: The conventional rotary cascade dryer. Arruda (2008) developed a general model for the drying process in a conventional rotary dryer that could be applied to any type of particulate material. This author found good agreement of the simulated results from this model with experimental data for fertilizer drying. However, Fernandes et al

    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

    Discrete Element Methods have been used extensively in processes involving flow behavior where modeling the individual particles is of particular interest. A rotary cooler is an application of one such process. Although the current analysis can be used to any type of rotary cooler or rotary dryer, this work is focused on the analysis of particles falling from lifters in a planetary rotary
