Iron ore concentrates are ground prior to pelletizing processes in order to increase their surface area to improve pellet resistance (Meyer, 1980). Size reduction operations typically include ball milling (Faria et al., 2019) and roller pressing (Van der Meer, 2015, Campos et al., 2019), which are applied to particles typically below 1 mm or …
