Application of population balance model to HPGR

2013-9-1  The new modeling approach for HPGR crushing is based on population balance model. The breakage rate of the particles was defined as a function of specific grinding force and material characteristics. The model was developed for a wide range of data acquired from hard rock and cement grinding but only a few data was presented in the paper.
