A semi-autogenous grinding (SAG) mill is dependent on rotation to carry the grinding media around the mill for minerals impact and attrition, as presented in Figure 1.It is an energy-intensive unit operation and requires extremely wasteful equipment in terms of energy utilization and consumption.

Since the early 1980s, we have been designing and manufacturing Semi Autogenous Mill (SAG Mill) and Autogenous Mill (AG Mill) under the Fuller-Traylor brand. Semi-autogenous grinding uses a minimal ball charge in the range of 6-15% while autogenous grinding uses ore only. SAG and AG Mills operate by lifting ore/grinding media and dropping it on ...

Processing is carried out in mills (ball, autoge ous, semi-autogenous). The grinding f differe t materials is an important industrial process in which the material is crushed and milled to a certain pre-defined size by the interac ion between material, grinding bodies, and grinding media.

Semi-autogenous Outotec 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.
