抄録

The newly developed brand Marra Mamba ore from Australia has a comparatively high water absorptivity, and since many fine ore is contained, if it is used as a raw material of sintered ore, it will cause the fall of permeability, and the productivity fall of a product sinter by the fall of the granulability. By blending nuclei particles with this Marra Mamba ore, the granulability and the permeability have improved sharply by processing them in a high-speed agitating mixer. This that point, about 25 mass% is suitable for nuclei particle mixture ratio to a high-speed agitated material.<br>Moreover, the granulability was improved by using the ore containing much 1-3 mm particles. As for this, it is considered that the granulation of a middle size ore domain is accelerated, because of the consistency of the particle size composition of the material processed and pot characteristic of high-speed agitating mixer.
