Determination of Moisture Capacity of Iron Ore for Sintering
Spraying water on to iron ore fines is the first stage as they are tumbled in a drum. The water penetrates into the iron ore particles and binds them together. As a result, the iron ore granules will have certain strength bearing friction and collision during the transportation, and the permeable bed will form during the sintering. It was reported that the strength of granules increases with increasing the water content in the mix. However, it is advantageous to minimize the water content used because energy is required to evaporate it during the high temperature treatment cycle. In order to optimize the water content sprayed into mixture of different iron ores, the moisture capacity of iron ore fines was measured with a novel and simple method in present study, the relationship between the moisture capacity with some other characters of iron ores were discussed. It was found that the mineral composition and the size distribution of the iron ore particles greatly influence the moisture capacity of the iron ores.
