While FEECO rotary dryers are custom designed around the material to be processed, the basis of a rotary dryer is somewhat standard, with customizations coming in terms of sizing, materials, mechanical components, and add-ons, among other items. The diagram on the next page shows some of the basic standard components found on a direct rotary dryer.
HOW ROTARY DRYERS WORK Rotary dryers use a tumbling action in combination with a drying air in order to eficiently dry materials. Most often, rotary dryers are of the direct conigura-tion, meaning that the drying air is in direct contact with the material. Some dryers, however, are of the indirect type, whereby the dryer is heated externally,
This paper shows how the problem of simulation and design of integrated direct rotary dryer and cooler can be solved in an algorithmic way. In the last few decades dryers and coolers are …

In this paper, an analysis of the optimal design for two-segmented flight is performed with the aim to obtain some practical recommendations for the design of a rotary dryer. Using a geometrical model, validated with experimental results, flight loading and unloading are studied over the range of every possible angle between the flight segments.
