A fluid energy mill is used for __________________?
Correct answer: C. Ultra-grinding
- A. Cutting
- B. Grinding
- C. Ultra-grinding
- D. Crushing
Explanation
A fluid energy mill uses high-velocity jets of gas to produce intense particle-to-particle impact, making it suitable for ultra-fine grinding. It is not primarily used for ordinary cutting, crushing, or coarse grinding.
