Thus, a semi-autogenous and autogenous grinding mill is preferred for grinding in mining industry on account of its extremely high availability rate, high throughput and low energy consumption. However, grinding in such mills becomes a complex process as the feed rate and mineralogical properties of the ore dictate the mill properties.

SAG mills use larger pieces of ore to break up the smaller pieces (autogenous — does it by itself). The larger pieces break down as well. To help the process along, eight-inch-diameter steel balls are added to the rocks as they tumble inside the rotating mill (semi-autogenous — gets some help from the steel balls).
