Advances in Discrete Element Method Application to

research Fuerstenau et al. 1973. A number of advancements were made in the application of this model to ball mill grinding. However, the same models could not be extended to semi autogenous grinding. Simply carrying out pilot scale SAG grinding is a very tedious task. At this time, the discrete element method appeared on the scene.

The number of current sensors required for high level number systems increases their costplexity. Power estimation can be used to eliminate current sensor requirements by inferring the PV power from other measurements. This paper presents a power estimation method for a CHB PV system with a Model Predictive Control MPC scheme.

SAG Mill Power Model Grinding Classification Circuits

Prediction of correct sag mill power consumption with a change in ore hardness, solid percent density to the sag feed, rpm of sag and PSD has always been very tricky. So far, I have used Austin Morrell model and Hogg Fuerstenau power model, but these models seem to work well only under certain boundary conditions.
