The ball mill consists of the mill base and the mill jar. There's one more important component to a ball mill, though: the media. The balls of heavy material which fall upon and crush the chemicals are called the milling media.

Ball milling is a way to exfoliate graphite using lateral force, as opposed to the Scotch Tape or sonication that mainly use normal force. Ball mills, like the three roll machine, are a common occurrence in industry, for the production of fine particles. During the ball milling process, there are …

Likewise, wheat straw milling using a vibratory ball mill for 8 h significantly changed the crystalline cellulose into an amorphous form and greatly facilitated the removal of lignin and hemicellulose from a wheat straw during the successive chemical pretreatment process .

I believe Bill indicated the potter in the video ball mills crystalline glazes, which may be why he can use plastic jars. But, I think you could use ceramic jars just the same. Couple take-aways from the video: nice use of (rejection?) letters as funnels and good use of Perrier
