  • [PDF] Investigation on the particle size and shape of iron

    An effect of a grinding method that is ball mill and high pressure grinding rolls (HPGR) on the particle size specific surface area and particle shape of an iron ore concentrate was studied. The particle size distribution was meticulously examined by sieve laser and image analyses. To measure the specific surface area of particles Brunauer-Emmett-Teller (BET) and Blaine methods were used.
