Induration of green pellets consists of three main steps namely (i) drying of green pellets (ii) firing of pellets at around 1300 deg C to sinter the iron oxide particles and (iii) cooling of hot pellets before discharging. During drying (temperature range of 180 deg C to 350 deg C) moisture content of the green pellet is evaporated.
In pelletizing plants that operate with wet grinding to reduce the particle size of the ore prior to the balling/pelletizing process it is necessary to dewater the slurry exiting the grinding mills to lower the moisture content in the ore. The pelletizing of iron ore normally requires from 8 to 10 moisture depending on the ore characteristics.
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 before dewatering
and Pellets. Vale is the world s biggest producer of iron ore and pellets raw materials essential to the manufacture of steel. Iron ore is found in nature in the form of rocks mixed with other elements. By means of various industrial processes incorporating cuttingedge technology iron ore is processed and then sold to steel companies.

Our iron ore pelletizing systems combine the best features of both technologies to provide the most modern plant and to produce pellets at the lowest cost and highest quality. Pellet plants sized from to 9MTPA. Engineering and design of complete plants from ore receiving to pellet discharge. Supply of the main pelletizing and indurating
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 lowgrade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing process
Modern iron ore pelletizing process operations may be divided into two main process sections feedstock preparation and agglomeration processes. In most plants the required particle size distribution (PSD) is obtained through the wet ball mill circuit.
The New Millennium plant sizes the ore coarser for sintering or finer for pelletizing which Tata performs at its European steel plants. "Ordinarily in North America pelletizing is an extension of the mining and beneficiation process " relates Ernest Dempsey New Millennium Iron Corp. s vice president of investor relations and corporate

Advantages of pelletisation Pellets are in high demand in the international markets fetching a premium price as they are ideal for blast furnace applications. When used in the rotary kiln pellets reduce the iron ore requirement to tons per ton of sponge reduce the travelling time and increase the sponge output by 2025 reduce coal consumption by 1520 and improve the metallization
Oct 22 2021feb 23 2013 introduction to iron ore pellets and pelletizing processes pelletizing is a process which involves mixing of very finely ground particles of iron ore fines having a size which is less than 200 mesh mm with additives like bentonite and then shaping them into near oval/spherical balls having size in the range of 8 mm to 16 mm in .
wet plant iron ore process diagram. 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 2. Our iron ore wet processing plants are proven to successfully
The average iron content of pellets is 63 percent. Process Description25 41 Processing of taconite consists of crushing and grinding the ore to liberate ironbearing particles concentrating the ore by separating the particles from the waste material (gangue) and pelletizing the iron ore

wet process iron ore pelletizing plants lokataw . In pelletizing a mixture of iron ore water and binder is rolled in a mechanical disc or Binder plays an important role in the success of the pelletizing process Wet compressive strength is a measure of how much load a pellet can bear and is will cause losses in plant efficiency in terms of both productivity and quality Read More
Depending on the ore type quality and its degree of degradation a washing and classifying plant can increase the iron content by two to five per cent while reducing the silica alumina titanium oxide sulfur and phosphorous content through removal of fines below mm by washing. For example decreasing the alumina content reduces the

Pelletizing disc (also known as disc pelletizer or pan granulator) is the equipment for processing powdery materials into round pellets with a certain strength. It can be used in the iron ore pelletizing plant of the steel industry or regarded as cement equipment applied in the raw meal pelletizing process of the shaft kiln cement plant.
In the last years pelletizing has been playing an important role in iron ore mining and in iron production (iron making and direct reduction). Some factors have contributed to this fact as
