The mill charge volume has a great impact on grinding efficiency. For efficient grinding, autogenous (AG) and semi-autogenous (SAG) mills need to be operated with the correct charge in order to maximize their throughput while avoiding overloading. The Outotec MillSense sensor system gives a precise indication of the mill charge volume.

Autogenous and Semi-Autogenous Mills . Rely on our proven track record of SAG and AG Mill superiority. Since the early 1980s, we have been designing and manufacturing Semi-Autogenous (SAG) and Autogenous (AG) Grinding Mills under the Fuller-Traylor brand. Semi-autogenous grinding uses a minimal ball charge in the range of 6-15% while autogenous
SAG mill liner development draws primarily on practical experience from SAG milling operations supported by computer-based modeling of charge motion in SAG mills and on established good design practice. Liner design needs to respond to the process aspects of mill liner action that are critical to good SAG mill performance, i.e., the impact of shell liners on the …
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.

Thissemi-autogenous mill, also calledsemi-autogenous grinding millor SAGmill, is mainly used togrindores and other particulate matter in different fields, like chemical industry, mining field, metallurgy industry, building material sector, and so on.
6") steel balls added to the mill (hence the name of semi autogenous milling). The steel balls can occupy from 10 percent to 18 percent of the mill capacity. Given the size and form of the mill, these balls are sent into free fall as the mill rotates, providing a combined crushing and grinding effect on the ore. One of the main reasons for
A detailed test work was carried out with an industrial semi-autogenous (SAG) mill in a copper plant in close and open circuits to specify the effects of ore characteristics and operational parameters on mill performance. In addition, the shape of mill product particles was studied to monitor breakage events as a function of ore strength.
What is a SAG mill? The structure of the SAG mill (semi-automatic grinding mill) and the AG mill (autogenous grinding mill)are exactly the same, except that a certain proportion of auxiliary grinding media such as steel balls or steel rods are added as needed. During the process of the AG mill operation, some ores with diameters greater than 20mm but less than 80mm are not …

An autogenous mill of ID 6.7. m and an effective grinding length of 2.1 m was fed with ore of SG 3.8 to 20% of its volume.. The mill was operated continuously 24 hours per day at 1200 t per day and 75% of the critical speed.The solids in the mill charge were at 80% solids. Estimate:1. The power consumption per tonne per day.
As with rod and ball mills liner designs for autogenous and semi-autogenous mills have been in a state of flux for a number of years. Operators continually search for optimum designs. Each mill application and each liner material coupled with varying mill diameters will produce a different internal wear pattern.
