Reduction ratio of crushers is the___________________?
Correct answer: A. Ratio of feed opening to discharge opening
- A. Ratio of feed opening to discharge opening
- B. Ratio of discharge opening to feed opening
- C. Determining factor for minimum dia of the feed and the product
- D. None of these
Explanation
The reduction ratio compares the characteristic feed size with the product or discharge size, so it is represented here by the feed opening divided by the discharge opening. A larger ratio indicates greater size reduction in one stage.
