Direct- VS. Indirect-Fired Rotary Kilns & 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 transfer. The most common form of internals is a lifting flight or “lifter ...
Direct vs. indirect heating technology - Solex
ROTARY DRUM DIRECT HEAT TRANSFER. Rotary drums are commonly used to remove moisture content from a free flowing bulk solid, by bringing the material in direct contact with a heated gas, commonly air. A rotary drum is a cylindrical tube, that slopes slightly downwards and rotates rapidly. As the product (ex. powder, fertilizer, sugar) enters the drum dryer, the rotating mechanism lifts the ...
