Simplify the crushing and grinding process; feeding particle size is 200-350mm and after the first autogenous grinding the product particle size reaches below a few millimeter.
The AG mill autogenous grinding mill is a medium-free grinding machine. In order to improve the processing capacity 2 -3 steel balls can be added also known as semi autogenous grinding mill or SAG mill. Raw ore or coarse crushed ore from the mine can be directly fed into the AG mill SAG mill for grinding.
Autogenous Grinding. a grinding process in which large pieces of the material to be ground—ores and rocks-serve as the grinding medium; the process is carried out in drum mills. In autogenous grinding a distinction is made between ore and ore-pebble grinding. Ore grinding is carried out in mills with a large diameter up to 12 m and short.
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.
