Investigation on Iron Ore Grinding based on Particle Size Distribution
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
Comminution and classification technologies of iron ore
Most of the highgrade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO) This involves multistages of crushing and screening to obtain lump (−315 + 63 mm) and fines (approximately −63 mm) products
