Process for the thermal treatment of granulated iron ore Combustion behavior of granulated coke breeze in iron ore

Feb 18 32 The wet granulated iron ore is initially conducted through a drying zone The ore leaves the drying zone at a temperature of 120 400 176 C The ore is then heated in direct contact with hot gas to temperatures of 700 1 100 176 C before being delivered to a reduction zone The ore coming out of the drying zone is fully or partially guided through a separating device so as to separate the ore into 1 Introduction Iron ore sintering is a very important process which produces sinter as a major burden for blast furnace ironmaking In this process iron ore and auxiliary materials eg fluxes unqualified sinter called return fine and coke breeze are mixed granulated and
