Vertical stirred mills are increasingly used for fine grinding applications in the mineral processing industry due to their high energy efficiency.
As a result, accurately modeling power draw has become an important area of research, as demonstrated by previous work including analytical modeling approaches.
In this whitepaper, we present the development of a coupled DEM‑CFD model designed to predict power draw under a range of operating conditions.
These conditions include variations in grinding media filling level, shaft speed, fluidization behavior, and changes in the grinding compartment configuration.
An extensive testing program using a specially equipped test mill has been conducted to validate the model.
