2019-9-10SAG mill Principle of SAG Mill operation. SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21. 6 7 The largest SAG mill is 42 12.8m in diameter, powered by a 28 MW.

Live ChatWith improved SAG mill control stability, the mill load can be optimized to increase crushing performance and produc tion capacity. Along with the potential for greater produc tion, BrainWave also allows you to operate your mill at maximum efficiency. Because a large amount of power is used just to keep the mill and its ball charge moving.
