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.
Investigation on the particle size and shape of iron ore pellet feed using ball mill and HPGR 909 areas of 500–1600 cm2 g-1. The concentrate must therefore be re-ground in order to prepare suitable pellet feed. High pressure grinding roll (HPGR) and ball mill are the most widely used
Jan 03, 2020· Ball mills are progressively used to grind the ores for particle size reduction and to liberate valuable minerals from the ores. The grinding of ore is a highly energy-intensive process [1,2,3,4].In this process, the size of the particle obtained depends on the energy consumption of the ball mill.
