Crushing efficiency of a machine ranges between __________________ percent?
Correct answer: A. 0.1 to 2
- A. 0.1 to 2
- B. 5 to 10
- C. 20 to 25
- D. 50 to 70
Explanation
Only a small fraction of the energy supplied to a crusher creates new surface; most is lost through friction, deformation, noise, and heat. Crushing efficiency is therefore typically about 0.1 to 2 percent.
