continuous direct heat rotary dryers

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 …
