Consequently the relationship of the autogenous work index to the power actually consumed in a large autogenous mill can be determined. If the power consumed in the 450 mm mill were 100 efficient then the relationship between the 450 mm mill andmercial mill would be a straight line as shown in graph No. 1paring it with the actual relationship as shown by the curve on the graph
The tare power empty mill power of 3.65 kW was determined for the mill prior to starting the tests. The specific power consumption determined by subtracting the mill tare power from the gross input power is the actual power input to the mill charge rock and/or balls.
The 15 lower media consumption in Mill II is certainly significant because media costs usually are in the range of 15 20 of total direct mill costs. The results at Cyprus Pima over the four year period from 1974 to 1977 show that total steel, consumption was 13 less using a semiautogenous ball mill circuit versus a conventional crushing rod mill ball mill circuit.

The torque
In autogenous grinding, one way to change the product size is to switch to semi autogenous grinding which will give a coarser product than autogenous grinding and usually at less power consumption per ton. The Cleveland Cliffspany referred to this in their paper on autogenous grinding. The Union Corporation in a paper on the reduction works at the Kinross Mine gives some data on

Scale Up in Sizing for Grinding Mills Scale up criterion is specific power consumption, i.e. the power consumed by the mill rotor itself minus all mechanical and electrical losses divided by the feed rate of solids. For the full scale mill, specific power is multiplied by the feed rate to get mill power.

The pover draw of an autogenous mill is directly proportional to the charge volume, which, in turn, is maintained by feed rate. This investigation showed no significant difference in the grinding power requirement, or the metallurgy of the product, with changes in volume. However, if an autogenous mill level is too high, centrifuging will begin.
