Minimizing profile error when estimating the sieve-size distribution …
In pellet manufacturing, green pellets are produced primarily from crushed iron ore in a rotating pelletising disk or tumbling drum, after which they are baked in a furnace to produce hardened black pellets. For quality control, manual sampling of the green and black pellets is conducted. Green pellets are fragile and cannot withstand …
