A particle size reduction model has been developed as the first component of an upgraded ball mill model. The model is based on a specific energysize reduction function, which calculates the particle breakage index, t 10, according to the sizespecific energy, and then calculates the full product size distribution using the t 10 t n relationships and the masssize balance approach.
