1. Introduction. Iron ore pellets are one of the significant sources of iron for iron and steel making due to their superior metallurgical performance, low energy consumption, and less emission of environmentally harmful dust and gases during the production process [1], [2], [3].The two primary raw materials for pellet production are hematite and magnetite concentrates.

Highpressure grinding rolls reached great popularity for pressing iron ore concentrates since its first application in the 1990s. For this particular application, mathematical models describing HPGR performance on the basis of operating conditions and feed characteristics have successfully been used by the authors to map industrialscale operations under controlled conditions.
