Description

From the development of a semi autogenous grinding model based on effective grinding rates and internal classification presented during the nineties (Magne et al, 1995) the state of the art of the mathematical structure of this model was updated, presenting the development of each sub -process from the inside of the mill in detail. The developed model was used to demonstrate its predictive capacity using results from SAG pilot tests on copper ores. After applying the model, the ability to replicate the results obtained from size distributions of internal load, product and total filling level with an error of less than 4% was demonstrated. This article presents, from a simplified approach and based on the observation of the phenomena at pilot scale, the first approach and details of how to use the model for the development of a grinding simulator being an alternative to the current state of the art.
