• Comparative Analysis of Grindability of Iron-ore and

    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.
