Jun 18, 2019 The variable that can be more readily controlled in a wet ball mill in operation in industry is solids concentration, with selected studies having been conducted for iron ores. Martinovic et al. [18] measured the breakage rates at solids concentrations between 72 to 82% for an iron ore and found that

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
