IRON-ORE MATERIAL AGGLOMERATING METHOD Russian patent published in 2017 - IPC C22B1/16 C22B1/243 

FIELD: metallurgy.

SUBSTANCE: method for agglomeration of iron-ore materials includes preparation of agglomeration charge components for sintering, composition, mixing with its wetting to 3-4% with water and pelletizing the agglomeration chrage in the drum, laying it on the sintering machine, igniting and sintering the agglomeration charge, agglomeration sinter processing. At that, during pelletizing the mixed charge is humidified to 6-10% with pulp, containing bentonite of a size not exceeding 0.1 mm, and with betonite consumption of 2÷18 kg/t.

EFFECT: increase of agglomerate impact strength, decrease of agglomerate abrasion resistance, increase of specific efficiency of the sintering machine and the yield growth of suitable agglomerate.
