Abstract

An application of limonite as grate-layer material in producing spherical agglomerate features that its layer thickness is 30-40 mm and its granularity is 10-25 mm. The raw materials for producing spherical agglomerate include returned ore (10-20 wt.%), calcium lime (2-10), lime stone (0-12), dolomite (0-12), solid fuel (3-7.5) and Fe-contained material (rest).
