High pressure grinding rolls (HPGR) are becoming an increasingly popular energy efficient solution for comminution of hard rock ores. A significant barrier to the increased adaptation of HPGRs is the current requirement for large amounts of sample for pilot testing. The primary objective of the research was to develop a DEM based computer model for an HPGR to analyze the particle behavior in
