design of a plant for Adanac Moly Corp. to include SAG and Ball milling. The hardness of each sample was measured in terms of SAG power index, SPI (for SAG grinding) and Bond Ball mill work index, BWi (for ball mill grinding). A further measure, the Minnovex crusher index, Ci was also measured for use in the CEET program to determine SAG

AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill. Because of the range of mill sizes available, AG/SAG milling can often be accomplished with fewer lines than in a conventional rod mill/ball mill circuit.
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 inefficiency factor to the power calculated for the rod milling stage only.

The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods, and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent.
