Estimation of Grinding Time for Desired Particle Size

The work carried out in this context focuses on three different samples of iron ore, viz., high silica high alumina, low silica high alumina, and low silica low alumina. The grinding process for all the three iron ores is carried out individually in Bond’s ball mill and the total retention time taken by each iron ore sample is calculated.Important advances have been made in the last 60 years or so in the modeling of ball mills using mathematical formulas and models. One approach that has gained popularity is the population balance model, in particular, when coupled to the specific breakage rate function. The paper demonstrates the application of this methodology to Optimization of Solids Concentration in Iron Ore Ball Milling

Iron ore pelletization ScienceDirect

The ratio in the output from the three main pelletizing technologies changes depending on practical circumstances, such as iron ore reserves, iron ore types, market demand, and required investment. The ratio for grate-kiln pellets has increased to 55.33% in 2011 from 7.21% in 2000, while the ratio for shaft furnace pellets has dropped to 42.05%Abstract. The application of vertical mills in regrind circuits is consolidated. This type of mill is now attracting interest in primary grinding applications, due to its higher efficiency when compared to ball mills, which are usually used at this stage. In this study, a coarse sample of iron ore was tested in a pilot scale grinding circuitVertical mill simulation applied to iron ores ScienceDirect
