Forum on Ball Milling A Study of Operating Data from Ball Mills Operating in Quebec, Ontario, Manitoba, and British Columbia

CIM Bulletin, 1957


IN 1953, Lewis (1) published an article which brought forth a great amount of discussion by grinding engineers. In his contribution to discussion the present writer (2) suggested that, for the most efficient performance of a ball mill, there must be a .definite relationship between Cn, per cent critical speed, and V p, per cent mill volume occupied by the ball charge. Later, he ( 3) was able to publish some grinding data from Wright-Hargreaves mill, which appeared to bear out this contention.
