The milling process – definitions Cutting speed,v c Indicates the surface speed at which the cutting edge machines the workpiece. Effective or true cutting speed, v e Indicates the surface speed at the effective diameter (DC ap).This value is necessary for determining the true cutting data at the actual depth of cut (a p).This is a particularly important value when using round …

Formula (32) is very convenient for milling calculations on ores of this type. Example: An ore contains 5% lead and 1% copper. The ratio of perfect concentration for a concentrate of maximum grade and recoveries of lead and copper would be: by (29) K perfect = 100/5.775+2.887 = 11.545 and % Pb in perfect concentrate = 11.545 x 5 = 57.7%

d = cumulative percentage on any mesh in the mill discharge, o = cumulative percentage on same mesh in the classifier overflow, s = cumulative percentage on same mesh in the classifier sand. The percentages through the finest screen may be used in place of the cumulative oversizes. Circulating load ratio = (d-o)/ (s-d) (10) Average 3.04.
