Ore Sinter - an overview ScienceDirect Topics

Sintering is made by charging a mixture of ore fines together with coke breeze, fluxes, in-plant returns and return fines onto a circulating grate, or sinter strand, and igniting the coke breeze contents in the surface. A flame front passes through the layer of the mixture over the strand length and agglomerates the mixture into coarse lumps of ...
