Sep 25, 2010 Grindability Index is calculated as, HGGI 13 6.93 W 200 mesh or HGGI 4.87 W 30 mesh 95.85. Where W is the weight of material passing through 200 mesh and 30 mesh, respectively. Grinding machine use eight 1 in. balls rolling on a stationary ring and driven from top by a rotating element.
As a result of comminuting iron ore and granite and ironore have grindability values of 0.061 grev and rock, it is important to determine the hardness and the 0.926 grev respectively. This confirmed that granite requires grindability characteristics of both materials so that more energy to be grinded.
