Autogenous mills can handle both wet and dry operations. In some applications that require the grinding of minerals, such as talc, asbestos, and mica, dry semi-autogenous milling is the preferred choice.
Fully-autogenous FAG and semi-autogenous SAG mills were first used on ores in the 1950s, but they were not seriously considered by the mining industry until the 1960s. By the 1970s, most designers of new plants considered AGSAG grinding, even if it was not used in the final grinding
The paper highlights the features of constructing a model of a wet semi-autogenous grinding mill based on the discrete element method and computational fluid dynamics. The model was built using Rocky DEM v. 4.4.2, ESSS, Brazil and Ansys Fluent v. 2020 R2, Ansys, Inc., United States software. A list of assumptions and boundary conditions necessary for modeling the process of wet semi ...

The Brazilian iron ore resources are shifting from high grade ores with good liberation at coarse sizes, to lower grade ores with good liberation only at finer sizes, requiring grinding down to a fine size to liberate and concentrate. Considering the very large throughputs required in the plants it is important to ensure the long-term economic and energy feasibility of this process.
