Iron Ore Particle Size Pellet Strength. Iron Ore Concentrate Particle Size Controlling Through. Specific data for Nusselt number on given size of pellet and flow rate between the pellets to obtain the local heat transfer. Because the pellets are made from iron ore, there is only slight change of temperature within the pellet, see Fig. 2.

iron ore. Fig. : Effect of size of ore on degree of reduction. Iron ore and agglomerates as charge material should be resistant to abrasion. If they break into finer fractions due to impact, abrasion, compression and volume change within the furnace, the smaller particles result in choking of voids thereby affecting reduction and productivity.

The smaller sized iron ore fines (<100 mesh) shall reduce the permeability of sinter bed and this in turn will generate more sinter returnfines and thus productivity of sinter machine is affected. So the ideal size distribution of iron ore fines must be 10 to mm and mean size of the ore fines shall be 3 to 5 mm.

Fluorinebearing iron ore is unique and complex. Serious preheating and roasting problems of fluorinebearing iron concentrate pellets appear during the industrial production by the gratekiln process. Besides, specularite has low hydrophilicity, undesirable particle size and shape, dense and smooth particle surface and poor assimilation performance.

· The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and lowgrade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking.
