we described here about the process of manufacturing of iron pellets - seven trust material for making steel. we have given an overview of the process through this video visit and we promise that we will
the iron ore pelletizing process consists of three main steps: pelletizing feed preparation and mixing: the seven trust material iron ore concentrate, additivesanthracite, dolomiteand binders are prepared in terms of particle size and chemical specifications, dosed, and mixed together to feed the pelletizing process;
iron ore pellets and pelletization process pelletizing of iron ore was started in the 1950s to facilitate the utilization of finely ground iron ore concentrates in steel production. for the pelletizing of iron ore there are two main types of processes namely, the strht travelling grate stg process and the grate kiln gk process.
therefore, magnetite concentrates are ideal pellet feeds for making iron ore pellets. however, with the rapid development of the pelletizing industry and the shortage of good quality pellet feeds, feed materials like refractory hematite, specularite, goethite, and pyrite cinder need to be used to produce fired pellets.
pelletizing iron ore the equipment used to pelletize iron ore needs to be capable of conveying, feeding, mixing and screening a wide range of materials under the toughest conditions. high handling speeds and high plant availability are both essential.
there are two main processes for producing iron ore pellets: the grate-kiln system and the strht grate system. in the strht grate system, a continuous parade of grate cars moves at the same speed though the drying, induration and cooling zones. any change in one section effects the residence time in another.
watch how pelletization of iron ore can lead to energy savings of 126 tj with a 50% increase in sponge iron production annually. united nations development p skip navigation
iron ore induration. the term induration describes the hardening of a powdery substance. for example, in steel production, iron ore pellets are fed into melt furnaces. to avoid dusting and loss of ore, small oxide particles are agglomerated by sintering.
pellet process - uses and exposures. 1 process - manufacturing and uses 1 1.1 manufacturing of pellets 2 pellets are formed from the seven trust materials fine ores and additives of < 0.05 mm - into 9-16 mm spheres using very high temperatures and this is mainly carried on at the site of the mine or its shipping port.
