Material Flow: - The material enters the dryer and first passes through the innermost drum. After the initial drying phase, it moves to the middle drum and then to the outer drum, undergoing additional drying in each pass. 3. Heat Source: - Heat is typically provided by a combustion system, such as a burner or furnace, located at one end of the drum dryer. The hot gases generated by the combustion process flow through the rotating drums, transferring heat to the material. 4. Air Flow: - The dryer is designed to optimize air flow through the drums, ensuring efficient drying. In a triple pass design, the material and hot gases move counter-currently through the three drums, enhancing heat transfer and drying efficiency. 5. Lifting Flights or Lifters: - Lifters are internal components inside the drums designed to lift and cascade the material as it rotates. This movement promotes good heat transfer and uniform drying.
