Abstract The authors analyze the influence of the semi-autogenous (SAG) mill parameters on the mill grinding efficiency, energy consumption and the tangential cumulative contact energy. This paper provides a new liner parameter design and optimization method, which offers theoretical guidance for the optimization design of liner parameters.
Semi-autogenous grinding (SAG) mills are presently one of the most widely used alternatives in the field of mineral size reduction as a result of their comparative advantages, such as higher processing capacity, lower physical space requirements, and lower investment and maintenance costs, as compared to conventional circuits.
To verify the accuracy of the DEM model, validation are carried out by simulation and experiment of Banisi and Hadizadeh (2007) within an industrial semi-autogenous grinding (SAG) mill used in the Sarcheshmeh copper ore dressing plant in Iran, and the inner size of which is 9.60 × 4.88 m. Inside the SAG mill, there are 60 steel rail-type liners, and each liner …

The SAG mill model of Napier-Munn et al. was used to describe the grinding process, along with a novel ball charge model and a mill-liner model. Using measurements of the mill charge weight and size-by-size solids discharge, Apelt et al. [26] used 29 measurements to estimate 37 states and 7 parameters with an extended Kalman filter (EKF).

autogenous grinding and ball mill grinding—these mills are known as Semi-Autogenous Grinding or SAG mills. Water is added to the ore during the grinding process. This creates 'slurry', which is then used to transport the ore throughout the remainder of the extraction process. SAG Mills constitute a recent innovation in terms of ore ...

Good control strategies ensure that a mill is operating as close to optimal as possible, resulting in significant economic benefits to an operatio...
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 …

Dramatic shortcomings of mill liner designs, especially of large SAG mills, such as rapid failure and even mill shell damage arising from impacting of the charge directly on the liner, and unsuitable spacing of lifter bars yielding unfavourable compromises between lifter bar height and liner life have ...
Rely on our proven track record of AG and SAG Mill superiority. 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.
