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.

grinding the iron ore in a ball mill. They are austenitised at 920 0 C for 60 minutes and given stepped austempering heat treatment 400 0C for 15, 30, 45, and 60 minutes followed by 300 0C for 120 minutes for each case. Grinding wear behaviour of these materials are assessed for wear loss in wet condition.
