Condition: new, Year of construction: 2025, functionality: fully functional, power: 11 kW (14.96 HP), A triple pass rotary drum dryer is a type of industrial dryer that is used to reduce or remove moisture from a material. It gets its name from the three rotating drums through which the material passes, each with a different purpose in the drying process. This type of dryer is commonly used in the production of various bulk solids, including minerals, agricultural products, and biomass. Here are the key features and components of a triple pass rotary drum dryer: 1. Triple Pass Design: - The material being dried passes through three rotating drums or cylinders, hence the term "triple pass." Each drum serves a specific purpose in the drying process. Guedpfxoq Nfuzj Aabsh 2. 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. 6. Retention Time: - The triple pass configuration allows for an extended retention time of the material in the drying system. This longer exposure to heat enhances the drying efficiency, making the triple pass rotary drum dryer suitable for materials with high moisture content. 7. Cooling Section: - After the material completes the three passes and reaches the end of the drum dryer, a cooling section may be included to reduce the temperature of the dried material before it is discharged. 8. Applications: - Triple pass rotary drum dryers are used in various industries, including agriculture (drying crops like grains), minerals (drying ores or concentrates), and biomass (drying wood chips or other organic materials). 9. Efficiency and Energy Consumption: - Triple pass rotary drum dryers are known for their high efficiency due to the extended drying time and effective heat transfer. However, they may have higher energy consumption compared to single or double pass dryers. When selecting a triple pass rotary drum dryer, it's essential to consider factors such as the type of material to be dried, required moisture reduction, and overall processing requirements. Proper design and operation are crucial to achieving optimal drying performance.
