### Combined DEM and SPH simulation of ball milling

A deeper understanding of the milling operation of ball mills helps mineral processing engineers to control and optimize them and therefore reduce their consuming power In this work the milling operation of ball mills is investigated using two methods i.e DEM and combined DEM SPH First a pilot scale ball mill with no lifter is simulated by both methods.
