The mixture is granulated with the addition of moisture and loaded to the travelling grate of the sintering plant.

Sintering: A Step Between Mining Iron Ore and Steelmaking

The function of an iron sintering plant is to process fine-grained materials, e.g iron ore fines, iron concentrates or secondary iron oxide wastes like millscale or collected dust, into coarse-grained iron ore sinter for use in charging the blast furnace. The sintering process is a pre-treatment phase in the production of iron.
