In the iron and steel industry the production of narrow particle size distribution psd for pellet feed making with acceptable liberation of valuables from the iron ore is very difficult this study has been carried out to achieve desired pellet feed with narrow psd and maximum liberation of hematite from the iron ore the iron ores have been collected from three different sources mines in
In ball milling the desired particle size is achieved by controlling the time applied energy and the size and density of the grinding media the optimal milling occurs at a critical speed ball mills can operate in either a wet or dry state while milling without any added liquid is commonplace adding water or other liquids can produce the
The particle size of the materials to be ground is 300 400mm sometimes even larger and the minimum particle size of the materials to be discharged can reach 01 mm the calculation shows that the crushing ratio can reach 3000 4000 while the ball mills crushing ratio is smaller
