Evaluation Of The Adhering Layer Ratio Of Iron Ore

Jun 09, 2018 Abstract. In iron ore sintering, the granulation process is the first and an important step. As the fine particles adhere to the coarse coke particles, the NO x emission generated from coke combustion may be expected to be influenced by that adhering layer.

Sintering behaviour of adhering fines and nucleus

Sintering Behaviour Of Adhering Fines And Nucleus

Sintering behaviour of adhering fines and nucleus particles of ores. Sinter quality and productivity are significantly influenced by the reactions occurring in the sintering bed. Formation of initial sinter melt from adhering fines and its interactions with coarse nucleus particles are the key sintering reactions. Hence understanding of these high temperature characteristics of iron ore is urgently needed.

Oct 01, 2018 Iron ore granules have a typical structure of a nuclei surrounded by an adhering fines layer 1, 8, 9. The nuclei is generally larger than 1 mm and relatively rigid, while the adhering layer is composed of 0.25 mm fine particles and some intermediate particles (0.25-1 mm) weakly bonded by water bridges , , . Therefore, it is reasonable to assume that the granule deformation is confined to

In addition, the adhering fines layer of C-type quasi-particles is growing by adhering of the fine iron ore and coke breeze uniformly until about 5 mm diameter of it. Consequently, it is thought that the coke content in the adhesion fines layer of C-type quasi-particle is almost constant regardless of its diameter.
