Introduction. Direct heat rotary driers are used to lower the moisture content of materials passing through the dryer. Materials are directly heated using heat from a combustion process; the fuel used is typically gas although pulverised coal, light fuel oil or waste process gasses could also be used.
Details
For many direct dryers, a heated airflow passes straight through the drying chamber and the dried product is discharged or separated from the outlet air stream. The air may be indirectly heated through a heat exchanger. Alternatively, the dryer can be directly-fired or supplied with flue gas from a burner.

The Difference Between Indirect- and Direct-Fired Dryers Operation. While both types of dryers are comprised of a rotating drum in which the processing occurs, these two types of dryers utilize very different methods to process material. Direct-fired dryers rely on direct contact between the material and process gas to efficiently dry materials ...
Details
Both direct rotary dryers and rotary kilns rely on direct contact between the material and process gas in order to process materials. Because rotary dryers operate at low temperatures, it is not necessary to internally line the dryer shell, and as a result, a wide range of internals can be installed to improve heat transfer.
