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.

What material characteristics should I consider when selecting size .

products in the minus 325 mesh and finer size range may be more suited for fluid-energy mills, while products coarser than 325 mesh may be ground more cost-effectively with a mechani- cal mill. Materials that need to be ground extremely fine and those that are temperature-sensitive, abrasive, or have a strict particle size.
