Investigation on Iron Ore Grinding based on Particle Size ...

2020-5-28  where F 80 is 80% feed particle size passing (μm), P 80 is 80% product particle size passing (μm), P i is the size of the mesh selected for the test, and Gpb is the grindability of the undersized product produced per mill revolution (g/rev).. After grinding the iron ore samples X, Y, and Z in the BBM, it was recorded that P 80, BWI, and RT varied for each iron ore sample as shown in Table 2.
