The SAG mill product is then crushed to passing 3.35 mm and is subjected to the Bond ball mill work index (Sd-BWI) grindability test to provide the total pinion energy at the specified grind size for mill design purposes, herein reffered to as micro ore hardness. The full SAGDesign test produces the SAG grindability.

## Mill (grinding) - Wikipedia

To calculate the needed grinding work against the grain size changing three half-empirical models are used. These can be related to the Hukki relationship between particle size and the energy required to break the particles. In stirred mills, the Hukki relationship does not apply and instead, experimentation has to be.
