2016/12/12 · The ball mill motor power requirement calculated above as 1400 HP is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution. The
• abrasion index for the feed material • maximum particle size of the feed to the mill • required F100 and F80 of the crusher product • percent moisture in the feed • proposed method of feed and discharge from the mill If this Title
In this research ball wear model was combined with the grinding model to optimise the milling stage of an industrial ball mill. Fig. 2 presents the flow sheet of the milling circuit but an open circuit determined by the region between point A and B which represents the industrial ball mill was considered for this research.
For each grain size there is an optimal ball size (Trumic et. al. 2007). The bigger ball in relation to the optimal one will have an excess energy and consequently the smaller ball mill has less energy necessary for grinding.
