Investigation on Iron Ore Grinding based on Particle Size
May 28, 2020 The iron ore blend takes RT of 13 min when grounded in the BBM for 250% circulating load with 80% passing particle size of 56 m. The blend iron ore sample obtained from the BBM is composed of a higher percentage of fines and is not suitable for pellet making. So, the grinding is carried out in the LBM by varying the retention time of the mill.
