Sphericity: When grinding media that is perfectly spherical is used in your mill, all gaps that form between them will be the same size. Once the media is no longer spherical, the force of the fluid or powder is not exerted equally; this can cause media to "tumble" in the mill, leading to some gaps being large and some small.
