Production rate _____________ with increased fineness, with a given energy input to the size reduction machine?
Correct answer: C. Decreases
- A. Remains unchanged
- B. Increases
- C. Decreases
- D. May increase or decrease; depends on the machine
Explanation
For a fixed energy input, producing finer particles requires more energy per unit mass, so the throughput or production rate decreases. This follows from the increasing energy demand as the desired product size becomes smaller.
