Grinding characteristic of a material is given by its___________________?
Correct answer: A. HGI
- A. HGI
- B. Angle of repose
- C. Shatter index
- D. Abrasion index
Explanation
The Hardgrove Grindability Index (HGI) indicates how readily a material can be pulverised, so it characterises grinding behaviour. Angle of repose concerns flowability, while shatter and abrasion indices describe other forms of material resistance.
