RESULTS AND DISCUSSIONS Performance of SAG Mill is measured in terms of throughput and energy consumption. Effect of total load and balls load on SAG mill performance SAG Mill total load and balls load have a marked influence on mill performance. The most important factors affecting the breakage efficiency are in fact charge volume and mill speed.
The choice of equipment and design of circuits has a significant influence on energy use.The practical energy efficiency of a milling process (the fraction of energy input used in breakage) is approximately 40% when using semi-autonomous grinding (SAG) equipment.
The SAG Mill is a machine added by Ender IO.It uses Micro Infinity (µI) to grind (or mill) items into their crushed variants, like Ores into Dusts.The SAG Mill has four output slots; recipes can have 1-4 different outputs, with different chances of obtaining those outputs. Uniquely, the SAG Mill can use Grinding Balls made from various materials to increase energy efficiency (resulting in ...
