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

2020-5-28  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 µm. 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.

Estimation of Grinding Time for Desired Particle Size ...

2020-1-3  Ball mills are progressively used to grind the ores for particle size reduction and to liberate valuable minerals from the ores. The grinding of ore is a highly energy-intensive process [1,2,3,4].In this process, the size of the particle obtained depends on the energy consumption of the ball mill.
