For the first stage of grinding, media will generally be in the 4″ to 2″ size (in some cases as high as 5″). In secondary finer grinding the initial charge will begin at around 3″ and in the case of balls will grade down to about ¾". Extremely fine grinding will dictate the use of 1½" and smaller balls. Grinding media is the working part of a mill.

At the same time, unlike modern production, «step» in diameter was 5mm (nowadays the standard step of size of grinding balls is considered 10mm). It should be noted that in the report, the nomenclature indicates "kernels", not "balls", but analysis of the situation of those times showed that there was no combat in that year.
