In case of grinding in a ball mill__________________?
Correct answer: D. All A., B. and C
- A. Wet grinding achieves a finer product size than dry grinding
- B. Its capacity decreases with increasing fineness of the products
- C. Grinding cost and power requirement increases with increasing fineness of the products
- D. All A., B. and C
Explanation
Wet grinding can produce a finer product, while increasing fineness lowers mill capacity and raises both power use and grinding cost. Thus, all the listed effects are valid.
