The ratio between the optimum moisture (W) and moisture capacity (mc) of a raw mix was determined as: W = 6.94 + 0.12 mc (2) The experimental data indicated a very high correlation between W and mc. Continuing with this research [49], the following equation has been proposed, based on earlier work [44], to calculate the optimum moisture (W) as ...
sinter plant in the NSSMC Kashima Steel Works, and it has ... as the sinter/ore ratio in the load. ... melts into hematite sinter, varying the. percentage of porosity (5-15%).
JSW Steel sinter plant receives iron ore fines of -10 mm size from Bellary - Hospet region which consist of 3 to 9% bigger than 10 mm and 30 to 35% smaller than 0.15 mm size fraction.
Optimum mean size of iron ore fines for good sintering process will vary from sinter plant to sinter plant since it is dependent on several factors but as a general rule higher mean size is better for permeability and hence helps in sintering productivity. Posted: 10 July, 2013 at 15:57 pm; Reply

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 low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. …
Indian iron ores are suffering from high amounts of alumina and loss on ignition (LOI), which are deleterious constituents in both the pelletizing as well as iron making processes. Iron ore fines utilized in pellet making consist of alumina in the range of 3.20–3.35% and LOI in the range of 3.50–3.70%. Detailed palletization studies have …
The ore mixture used in Polish sinter plants is based on hematite ores and magnetite concentrates [2,3]. All these raw materials differ significantly in terms of their chemical properties and grain size distribution which may lead to deterioration of the mixture sintering conditions at the sinter belt grate and cause negative environmental impact.
