SAG Mill - Official Feed The Beast Wiki. Better capacitors increase the machine's maximum energy usage rate and thus processing speed, as well as the internal energy buffer. A SAG Mill is processing Copper Ore. Grinding Balls. Grinding Balls are consumable items that can be placed in the top-right slot of the SAG Mill's GUI.

Crushed ore will be reclaimed from the coarse ore stockpile, via variable speed apron feeders, directly to the SAG mill feed conveyor which will transport the ore to the SAG mill feed chute. Process water will also be added to the SAG mill, via the SAG mill feed chute. The variable speed SAG mill will operate with a nominal ball charge of 10% v/v.
