  • MODELLING AND SIMULATION OF THE GRINDING

    A grinding model developed at ‘El Pilon’ mine using JKSimMet (Version 4) was used to simulate three different milling designs. The objective of these simulations was to investigate a new design of the grinding circuit with an additional ball mill to increase both grinding throughput and fineness.
