Sinter plants European Commission

By sintering, the pelletisation of finegrained, smeltable ores, iron ore in particular, to compact lumps by heating nearly to the melting or softening point is understood Melting tendencies at the grain boundaries lead to a caking of the material Before the sintering, the various substances are first mixed and, if desired, granulatedThis can take place in shaft furnaces, rotary kilns or on a travelling grate Pelletising plants are generally located at the iron ore producers Sintering (caking) is carried out using strand sintering plants with strand widths of over 4 m and strand lengths of over 100 mSteelmaking Stahlinstitut VDEh

Iron Ore Pelletizing Process: An Overview

As shown in Figure 1 , China presents the largest production capacity, followed by the United States and Brazil The iron ore pelletizing process consists of three main steps: 1 Pelletizing feed preparation and mixing: the raw material (iron ore concentrate, additivesSintering In order for the pellets to achieve their final properties, they have to be sintered, which means that the pellets are heated so that the iron ore particles partially melt together After the pellets have been sintered at approximately 1,250°C, they can cope with a load of up to 250 kg CoolingPelletizing LKAB
