Comminution - Wikipedia

High-pressure grinding rolls have an important role in several iron ore pellet feed preparation circuits. Modeling and simulation are potentially useful tools to improve their performance, but the applicability of mathematical models from the literature in this particular application has not yet been demonstrated, although the model by Torres and Casali has been identified as having good potential.

As a result of comminuting iron ore and granite and iron‐ore have grindability values of 0.061 g/rev and rock, it is important to determine the hardness and the 0.926 g/rev respectively. This confirmed that granite requires grindability characteristics of both materials so that more energy to be grinded.

Following fine crushing, the ore is directed to dry cobbing, which is a dry magnetic separation process used to reject the portion of the ore that does not contain sufficient magnetic iron. The ore not rejected during dry cobbing is sent to a series of wet grinding and concentrating processes to separate, concentrate, and recover the iron from the incoming ore.
