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.

Iron ore pellet feed need a distribution size of minus 106 µm from fine grinding. As separation circuits reduce the fines fraction to less than the required specific surface area ( Blaine cm2/g), it is necessary to regrind concentrates to facilitate generation of a suitable pellet feed for further treatment in the balling and firing steps.
