The semi-autogenous mill is a new type of grinding equipment with both crushing and grinding functions. It has the advantages of simple process flow, small investment, short construction cycle, and easy operation. It can directly grind raw materials or coarsely crushed materials to 0.074mm. The grinding ratio can reach 4000-5000, which is ten ...

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.

Wet Semi-Autogenous Grinding Mills. The primary mill liner task force was formed in 1977. Its function was to improve the operating costs and milling efficiencies of the ten 8.2-m x 5.5-m (27 ft x 18 ft) wet SAG mills that were operating at the time. The SAG mills are driven by two 3500 HP motors drawing a total of 5450 kW at 76% of critical speed.
