If you are talking about the 83mm Ceado E37S in classifieds, they are definitely 83mm flats….if you are talking about a different grinder hen hopefully this clarifies it for @pbg
pbg Its in the classifieds at 525 with a ‘tube’ for single or small dosing…
You can single dose it, but it’s ideal mode of operation is as a hoppered grinder. I’s a good grinder, don’t discount it.
