Simulation and optimization of a two stage ball mill

The two stage ball mill grinding circuit run in a molybdenum mine is simulated and optimized based upon a mathematical grinding model using the population balance approach. The results of the batch grinding tests showed that the specific rates of breakage in wet grinding are substantially different from dry grinding.
