Sep 25, 2010 The calculation of Hard Grove Grindability Index indicated increase in the ease of grinding of microwave treated iron ore than the untreated which is also confirmed by specific rate of breakage (S i) values. Consequently, it was concluded that the microwave assisted grinding was produced good results particularly for grinding characteristics.
As a result of comminuting iron ore and granite and ironore 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.
