Table 2 Investigated DEM parameters with their low, middle and high values (\(\:{\mu\:}_{s}=\) coefficient of sliding friction, \(\:{\mu\:}_{r}=\) coefficient of rolling friction, \(\:{C}_{r}=\) coefficient of restitution). The underlined values for pellet-pellet and sinter-sinter parameters used for pellet-sinter interactions.
