Grindability index of a coal is 100. It implies that the ___________________?
Correct answer: D. Coal can be easily pulverised
- A. Coal can be pulverised with great difficulty
- B. Coal can't be pulverised
- C. Power consumption in grinding the coal will be very high
- D. Coal can be easily pulverised
Explanation
A high grindability index means the coal breaks down readily during pulverisation and requires relatively less grinding energy. Therefore, an index of 100 indicates easy pulverisation.
