So to ensure that all the ore gets reduced and liquefied around the same time the maximum size should not be much more than 10 mm. Ideally it should be around 15 mm to 16 mm. However if the iron ore is crushed to a maximum size of 16 mm, at least 75% will be less than 9 mm and cannot be directly used.

ore crushing size classification

Comminution is particle size reduction of materials. Comminution may be carried out on either dry materials or slurries. Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on run-of-mine ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material.
