Pellet Plant Process. Raw material iron ore fines are fed to Iron ore grinding system (IOGS – 160 t/h) for grinding the ore to 85% -200 mesh. We use the wet grinding process for this. The slurry produced is then fed to filter press.
The process uses coal gas for pre-heating & for partial reduction. Hematite / limonite / goethite ores get converted into magnetite ore in 1-10 minutes depending on the size of iron ore, at temperatures of 500-600 degree C. The left-over heat, after reduction, is utilized for 3 stage pre-heating of iron ore.
The moisture content in green pellets with 0.5% bentonite was varied between 7.3% and 9.4%. By increasing the bentonite dosage up to 1.5%, the moisture range suitable for balling could be expanded up to 10.5%. Results from individual micro-balling batches are reported below.

The average iron content of pellets is 63 percent. 11.23.2 Process Description2-5,41 Processing of taconite consists of crushing and grinding the ore to liberate iron-bearing particles, concentrating the ore by separating the particles from the waste material (gangue), and pelletizing the iron ore ...
High Pressure Grinding Rolls ("HPGR") are applied in all stages of iron ore size reduction, from coarse ore grinding down to pellet feed preparation. In closed circuit operation, fine grinds can be achieved using HPGR in combination with dry or wet classification or a partial product recycle without classification. For fine product cuts,
At the Swedish plants, grinding is a wet process. In the Dutch plant grinding is carried out at relatively high temperatures (approx. 100°C). In the wet process additives (olivine, dolomite and/or limestone depending on the end product) are ground and then added to the ore slurry, typically at a level of 3 to 3.5%, before de-watering.
The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been …
etc. are required. In wet grinding process, equipment i.e. ball mill, cyclones, slurry pumps, thickener, filter press, etc. are required. In dry grinding, coal / lime stone/ additives is added with iron ore fines for grinding in ball mill. 2.2.2 Pre-treatment process of additives Additives i.e. Lime stone, dolomite, coal/coke are required to be ...
Figure 1: Iron pellets. The pelletizing process is a process which contains numerous sub-processes, or process segments. On the way from the mine to a final product, the iron ore goes through the following main process segments: 1) …
The wet compressive strength of green pellets was determined to be 1.4-1.5 kilograms per pellet. The porosity of burnt pellets at different temperatures was determined between 16% to 38%. The firing process of green pellets provided discrimination between the outer layer and the central part of individual pellets.

Our heavy-duty iron ore balling drums are relied on by some of the industry's top producers to process iron ore fines into pellets for the steelmaking process. The use of a disc pelletizer is a popular alternative approach to pelletizing iron ore …
iron ore. His process involved grinding taconite to remove gangues and upgrading the iron ore (i.e., an ore beneficiation process). The resultant high-grade ore is in the form of fine particles, as small as 0.1mm or less, which are not suitable for sintering. This issue led to the use of pelletizing. Pelletizing plants are expected to play an
Iron ore from M.G.Mohanty mines and charcoal were used in the experiment .Analysis of the iron ore showed that it contained 63.7%Fe, 1.6%SiO 2, and 1.4% Al 2O3. The reaction carried out in the experiment is mainly of direct reduction because here we …
The iron ore pelletizing process consists of three main steps: 1. Pelletizing feed preparation and mixing: the raw material (iron ore concentrate, additives anthracite, dolomite and binders are prepared in terms of particle size and chemical specifications, dosed, and mixed together to feed the pelletizing process; 2.
As a part of the pelleting process, loose materials are converted into compact pellets through the applica-tion of pressure and heat. Compressing the structure increases its mass by a factor of 10. For example, in pellets with a diameter of 3 mm, the density will in-crease up to 30 mm. This increase provides advanta-
