Sinter plant - Wikipedia

Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace. The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent materials to fuse to.

Development of a method for evaluating raw materials for use in iron .

Kumba Iron Ore identified a need to develop a new test method to evaluate iron ore in terms of lime assimilation. Lime is added to iron ore to improve the porosity and to obtain the correct sinter strength and permeability for use in the blast furnace. If the sintered ore does not have adequate strength, a large amount of fines.

Kinetics of iron ore sinter feed granulation - ScienceDirect

The kinetics of iron ore sinter feed granalation were shown to have a major impact on granule size distribution. At laboratory scale, it was shown . at an operating sinter plant. For scale-up purposes, the required residence time for granulation was predicted to be inversely proportional to the square root of the drum diameter.
