High velocity grinding and classification system

Sri

hi, i am a new fluent user. my system is a combination of high speed jet milling, dry air classifier & filtering system. The high impact collision between solid particles & air produces fine products & further the products are classified in the classification & filtering system. i need to explain & quantitatively show the mechanism within the mill & further relate it to the breakage kinetics & product quality in terms of fineness for example. i need to relate the input quality (raw material) with the output (product characteristics). How could i achieve this? i need to use 2d as well as 3d multiphase flow. Please kindly help me. thanks.
