Abstract

PURPOSE: To make the porosity of porous iron ore pellets uniform by blending iron ore with a combustible substance after which the blend is dry pulverized, pelletized, freed of the combustible substance by burning, and fired.
CONSTITUTION: Iron ore is blended with a combustible substance such as sawdust, petroleum coke or coal and dry pulverized with a ball mill, a rod mill or the like. The pulverization degree is about 100μ in the iron ore and ≤0.5mm in the combustible substance. The resulting mixed powder is pelletized by a known method together with a binder and water, and the combustible substance is burned to form pores in the pellets, which are then fired.
