Rotary dryers are widely used in chemical and mineral processes due to their flexibility and simplicity of operation. Nevertheless, the comprehension of the basic phenomena taking place in this type of dryer is still of great interest. In order to better understand the phenomenological behaviour of the process and to assess product moisture control strategies, a complete dynamic simulator of a mineral concentrate dryer has been developed The simulator is calibrated with industrial data and consists of a furnace model, a solids transportation model and a gas model, including the heat and mass transfer phenomena. The dryer simulator was shown to adequately represent the dynamic behaviour of an industrial rotary dryer.
