Application of value engineering techniques to grinding process modelling led to the identification of two basic functions of theball mill-classifier circuit. In terms of a specified circuit product size which is used to differentiate between “coarse” or oversize material and “fines” or undersize material, these basic functions are (a) breakage of the coarse material and (b) removal ...
The equation below shows the relationship between ball mill grinding efficiency and material fineness:K d = G 2 /G 1 = (d 1 /d 2) X (1) *Note. K d: the relative productivity of the mill; G 1 & G 2: respectively represent the mill output (T / h) when the feed particle size is d 1 and d 2;Read more +

Functionalperformanceanalysis ofballmilling has been described previously by Mclvor. “Coarse” versus “fine” or product particle cut-off size is first selected, usually equal to some benchmark passing size of the circuit product (e.g., 80%). The function of the grinding circuit is to generate new product size material (or “fines”) from “coarse” particles in the circuit feed ...Read more +
An increase of over 10% inmillthroughput was achieved by removing theballscats from a single -stage SAGmill. These scats are non- sphericalballfragments resulting from uneven wear of balls ...Read more +
Based on motion and impact analysis, a theoretical model is presented for optimization of grindingperformanceof a tumblingball mill. The motion ofballmedia in the tumblingball millis analyzed. The impact parameters of theballmedia caused by the falling motion are deduced. The impact and attrition grindabilities are studied. The grindingperformanceis expressed as the proportion of ...Read more +

Themilldischarge from thesemillsconsists of slurry, which goes to theball millsfor further grinding, and coarse pebbles/rocks, which are crushed and sent back to themill. To maximize the capacity of these circuits, the general practice is to use grates with pebble ports (reaching 100 mm) instead of normal grate openings to increase the ...Read more +
The final plan was to increase theballcharge in the SAG andball millto 10% v / v and 27% v / v, respectively; set the upper limit of the operating power in theball millto 5800 kW; use a TRIO TC Series crusher (without a power-/feed rate–controlling device, but with a feed bin) to crush pebbles for recirculation back to the SAGmillfeed ...Read more +
