SAG vs. AG Mills: Understanding the Key Differences
网页SAG mills and AG mills have different definitions and operate differently. SAG mills use a combination of steel balls and rock particles as grinding media, while AG mills use only the ore itself. Both types of mills are used for grinding ore in mineral processing operations, but SAG mills are larger in size and can grind larger quantities of ore.

Ball Mill (Ball Mills Explained) saVRee saVRee
网页Multiple stages may include a rod mill followed by a ball mill (two stage circuit), or a semi-autogenous grinding (SAG) mill followed by a ball mill (two stage circuit). Smaller plants tend to add extra crushing stages in order to operate a single grinding stage only. If a ball mill uses little or no water during grinding, it is a ‘dry’ mill.
