All minerals were ground through 200 mesh and a screen analysis was performed to determine the size distribution. Mineral surface area was calculated based on the size distribution and the assumption that the particles were spherical. grinding-media-chemical-analyses-of-mineral.

Selecting Ceramic Grinding Media: Part 1 Theory - Wiley Online .

In the mining industry where large volumes of grinding media per mill are re- quired, media wear versus cost is a key optimization consideration. Quantifica- tion of in-plant media wear is, however, often problematic. It can be done indir- ectly via small-scale laboratory mill tests or potentially via measurement of the physical.
