Iron ore pelletization
In some cases, ball milling is used before HPGR when the pellet feed is too coarse or too hard for saving grinding costs and improving balling characteristics of the pellet feed. For example, a wet ball mill plus an HPGR circuit was installed in WISCO Minerals' pellet plant in China to pretreat Brazilian specularite concentrates. 15.3.2.3.
