Height of the flights in the rotary drier is in the range of___________________?
Correct answer: A. 0.08 to 0.12 d
- A. 0.08 to 0.12 d
- B. 0.02 to 0.05 d
- C. 0.2 to 0.5 d
- D. 0.5 to 0.6 d
Explanation
Dryer flights are typically shallow lifting elements, with a height of roughly 0.08 to 0.12 times the drum diameter. Much larger values would cause excessive lifting and poor cascading of the solids.
