When calculating rod mill power for a rod millball mill circuit do not allow for improvement in the ball mill performance due to receiving rod mill feed If the rod mill feed is produced with open circuit crushing apply a 12 inefficiency factor to the power calculated for the rod milling stage only If the rod mill feed will consistently be

In Mineral Processing Design and Operations Second Edition 2016 831 Rod Mill Charge Rod mill charges usually occupy about 45 of the internal volume of the mill A closely packed charge of single sized rods will have a porosity of 93 With a mixed charge of small and large diameter rods the porosity of a static load could be reduced even further
Figure 82 shows a flow sheet where the rod mill is in open circuit and the ball mill is in closed circuit with a classifier This is a normal setup as the primary function of a rod mill is to provide a uniform sized feed to the ball mill Figure 83 shows that the rod mill product is classified and a more uniform feed size is therefore discharged to the ball mill whose primary function is
As the heavy rod charge transmits a considerable force to each rod a rod mill can not be built too big A shell length above 6100 mm can not be recommended As the length to diameter ratio of the mill should be in the range of 1215 the biggest rod mill will convert maximum 1500 kW
Under given load and particle size requirement capacity is a function of mill length and diameter Q kLD 2N N is related to mill diameter which decreases with larger diameters k a constant equal to π 4 A chart showing rod mill capacity vs mill diameter image
