Rittinger's number designates the new surface created per unit mechanical energy absorbed by the material being crushed. Larger value of Rittinger's number of a material indicates its________________?
Correct answer: A. Easier grindability
- A. Easier grindability
- B. Poor grindability
- C. High power consumption in grinding
- D. None of these
Explanation
Rittinger's number measures new surface produced per unit energy, so a larger value means more surface is obtained for the same energy and the material is easier to grind.
