The reduction ratio for fine grinders is_____________?
Correct answer: D. As high as 100
- A. 5-10
- B. 10-20
- C. 20-40
- D. As high as 100
Explanation
Fine grinders make a large size reduction in one stage, so their reduction ratio may reach about 100. Ratios of 5 to 40 are more typical of coarser crushing or intermediate size reduction.
