SAG mills (semiautogenous grinding mills) liming
Semiautogenous mills or SAG mills, as they are often called, can accomplish the same size reduction work as two or three stages of crushing and screening. Often used in grinding at modern mineral processing plants, SAG mills reduce the material directly to the desired final size or prepare it for the following grinding stages.

Grinding Mills an overview ScienceDirect Topics
In SAG mill operation, the grinding rate passes through a minimum at a “critical size” (Chapter 5), which represents material too large to be broken by the steel grinding media, but has a low selfbreakage rate. If the critical size material, typically 25–50 mm, is accumulated the mill energy efficiency will deteriorate, and the mill feed rate decreases. As a solution, additional large
