  • Development of a Novel Grinding Process to Iron Ore

     · The earliest industrial application of high pressure grinding rolls (HPGR) at comminution was in 1984 in the cement industry. Since then the equipment has been widely applied in mining activities. Despite the rapid spread across the industry several challenges are still present in the equipment s application especially considering the complex ore breakage behaviour reported for this process.

     · The feed samples of X Y and Z iron ores were ground in the BBM (ball mill refers to a BBM of size 300 mm 300 mm with smooth liners) to identify the PSD BWI and RT of each ore. Grinding experiments were conducted according to Bond s standard test procedure .For each iron ore sample the RT taken to produce 250 circulating load in the BBM was measured by a new method.
