Variability Study of Bond Work Index and Grindability Index on Various Critical Metal Ores

open access: yesMetals, 2021
It is a well-known fact that the value of the Bond work index (wi) for a given ore varies along with the grinding size. In this study, a variability bysis is carried out with the Bond standard grindability tests on different critical metal ores (W, Ta ...

Grindability of Ti−Nb−Cu Alloys for Dental Machining Applications

open access: yesMetals, 2022
We developed high-strength Ti−Nb−Cu alloys and investigated their grindability. The grindability of each alloy was evaluated based on the volume of metal removed per minute (grinding rate) and on the ratio of the metal volume removed to the volume of the
