Influence of the material properties of iron ore sinter ...

The effects of feed properties on the granulation of iron ore sinter feed have been studied using simplified sinter mixes. A measure of granulation effectiveness, x 0.5, has been defined as the particle size at which half the particles act as adhering particles and half as nuclei particles.High values of x 0.5 correspond to large mean granule sizes. . The granulation effectiveness is a strong ...
