In a roll crusher, the specific power consumption and the production rate is affected by the_________________?
Correct answer: A. Both A. and B.
- A. Both A. and B.
- B. Differential roll speed
- C. Reduction ratio
- D. Neither A. nor B.
Explanation
Reduction ratio changes the work required per unit of crushed material, while differential roll speed changes the relative sliding and shearing action. Both therefore affect specific power consumption and production rate.
