Hi Janet,
A pot mill is a ball mill is a tumbler is a jar mill. All work on the same
principle. I have a triple decker jar mill (rarely use it !), which was
used in the paint industry to break up coarse material. Top rollers were
large enough to hold a 44 gal/200 litre drum. Same as a ball mill, for
grinding glazes. The tumbler is generally used in the lapidary industry,
for polishing semi-precious gemstones, with various grades of grit, and
polishes. There is the tumbler which revolves on the rollers, and there is
the vibrating tumbler, which is similar in motion to a vibratory sieve.
Cheers. Graeme.

Is this "pot mill" a container of some description set up on
rotating rollers? If it is, it sounds like it could be a "jar
mill" to me...? At least that is what I know "small" rotating
set-ups with a lidded vessel (jar or container) to mill materials
or polish stones to be...
Or is this just applicable in the UK? Another instance of
speaking the same language, but divided by it? Whatever... It is
highly confusing for us English speakers, let alone those with
other mother tongues. A flour mill grinds grain and produces
flour, so a pot mill produces pot? And a ball mill produces...
Well, perhaps we better not go down that path... Bad enough
thinking of cremating cats in kilns...
