The power in kw required to turn a ball mill is approximated by p 0.073 j m n where d is the internal diameter in metres, j is the fraction of the mill volume occupied by media, m is the total mass of media in the mill, in tonnes, and n is the mill speed, rpm.
Predictions for different sag and ball mill-based circuit configurations.Existing power-based calculations for comminution circuits most modern grinding circuits consist of a primary sag mill and.
Foundation design criteria for sag mill and ball m.Ball mill an overview sciencedirect topics the ball mill accepts the sag or ag mill product ball mills give a controlled final grind and produce flotation feed of a uniform size ball mills tumble iron or steel balls with the ore the balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds the feed to ball.
Classify the agsag mill product into two products the phantom cyclone overflow that is similar to the final ball mill product, and the phantom cyclone underflow is then used as an adjusted ball mill feed for the ball mill power calculation.This technique is specifically suitable for model-based calculations, as it requires efficiency curve.

Ag - autogenous sag semi-autogenous mill design calculations.Obviously, the sag mill is consuming more and the ball mill less power than was predicted by the empirical method, but the overall total is 995 of the predicted total exampl the hemlo gold project of teck-corona 1000 mtpd provides an example of mill sizing using the empirical.
Sag mills mimic the same shortcoming.It follows that in order to obtain the speci c energy se to achieve a certain transfer size, based on the 80 per cent passing value, an inef ciency factor must be applied to the se of single stage ball mills, rod mills or agsag mills when calculating power according to the bond third theory method.
