Understanding Reactions in Iron Ore Pellets

Understanding Reactions In Iron Ore Pellets

The induration furnace for iron ore pellets was originally designed to process concentrates with high contents of magnetite. To support the use of haematite concentrates, internal fuel was added to the pellets in the form of ground coke breeze or anthracite. To ensure that the addition of coke breeze was not excessive, the heat of magnetite equivalent or heat of magnetite equivalent HME ...

During travel of the pallet constructions 16, cooling air is forced up through the pallets 16 to cool the iron ore pellets. The operation and structure of annular cooler 10 is well known in the art and therefore need not be described in detail herein. Referring to FIG. 2 a prior art pallet construction 16 is shown.

Mathematical modelling of wustite pellet reduction grain

Mathematical Modelling Of Wustite Pellet Reduction Grain

A mathematical time-dependent and non-isothermal model has been carried out on the basis of the grain model to study the behaviour of a wustite pellet undergoing chemical reactions with reducing gases. The behaviour of wustite pellet reduction analysed by the grain model has been compared with unreacted shrinking core model USCM. The results show, unlike the grain model, USCM cannot properly ...
