Ball mill
Ok, In a standard ball mill, you (usually) use metal balls as a medium for grinding. In a SAG mill, it is a Semi Autogenous Grind, where less balls are used, and the substance in the mill acts as it's own grinding agent. And dare I say it, In a FAG mill (Fully Autogenous Grind) they use no balls at all.

Ball size or ball mass – what matters in organic mechanochemical
Ball mass is an important parameter that is known to have an influence on the outcome of a mechanochemical reaction induced by ball-milling. A standard way of modifying the ball mass is to change the size of the ball made of the same material. In this case, however, a change in mass is accompanied by a simul Editor's Collection: …

Ball size. All balls should be the same size. To allow a stable cascade, ball diameter should not be much larger than 20% of the jar diameter. Smaller balls have more surface area and will have more strikes per revolution allowing for faster milling, but each strike has less energy, reducing effectiveness against harder materials. Larger balls ...

Here's a shot of some stainless steel media and ceramic media. The stainless steel must be spark-resistant, non-magnetic steel in the 300-series. Alloys 304 and 316 are the most common stainless steels of this type. High-density alumina ceramic media is the type I've heard of most often being used in ball mills.

Ball Milling
Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134–141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].
