摘要：

Until now most of the design methods for cascading rotary dryers have been either empirical or purely theoretical. A theoretical model is presented which simulates the operation of both cocurrent and countercurrent rotary dryers. It relies on pilot plant and bench scale tests to determine the values of parameters which describe respectively the transport of solids through the dryer and the drying rate of the feedstock. A procedure is outlined for using the model to scale up from these pilot-plant and bench-scale tests to full-scale dryers.
