The iron ore and additives with given moisture content are pelletized (formed into small balls referred to as green balls or green pellets) in a balling device. This could be a balling drum or a balling disk Pellets of various sizes exiting the balling device are discharged afterward on a deck of rollers, the roller screen, for removal of the pellets that are not within the sizing range.
Different from pelletizing which mostly use physical ways to cut plastic, it adopts pyrolysis technology to get fuel oil and carbon black from waste plastic, so as to recycle the plastic. But similar with the waste plastic recycling pelletizing machine, it is also an eco-friendly plant.
Iron ore pellet feed fines (PFF) The iron ore pelletizing process is marked by spherical pellets in a nar-row grain size distribution ranging between 9 mm and 15 mm. The raw material in the process consists of iron ore ( 100 μm), binders (i.e. ben- tonite) and additives such as coal dust.
Recycling Technologies Group provides machinery that turns wood waste into pellets. The machinery accepts large and small pieces of wood that have been dried to the desired moisture content. They are then shredded into chips and begin the pelletising process. Pellets are a clean, green
The balling area is where the powdered ore is mixed with water and rolled in rotating drums to create spherical balls. The green balls are spherical agglomerates nominally 12.5 mm in diameter, formed by rolling a moist mixture of finely ground iron ore concentrate, binder and sometimes a flux.

iron processing Use of a smelting process to turn the ore into a form from which products can be fashioned. Instead, concentrates must be agglomerated by pelletizing, a process that originated in Sweden and Germany about 1912–13 but was adapted in the 1940s to deal with low-grade taconite ores found in the Mesabi
Pelletizing Equipment Pellet is one of the important methods of powder ore agglomeration. Firstly, the powder ore is added with appropriate amount of water and binder to make a green ball with uniform viscosity and sufficient strength. After drying and preheating, it is calcined in an oxidizing atmosphere to form a pellet and form a pellet.
The pelletizing plant (capacity 3.3 mln tons/ yr) operates on a variable mixture of 6 to 10 widely different ores. A bedding system ensures that during about 1 week a constant and homogenized ore mixture is fed to the plant. The ore mixture is dry grinded by means of 3 ball-mills
into spheroids, called green balls, approximately 12mm in diameter. The green balls are fired into product pellets. The pellets are used as the raw materials not only for blast furnaces but also for gas-based direct reduction furnaces, the process becoming popular among natural gas producing countries.
(2) Addition of a clay-rich layer to green ball surfaces. This approach is a novel idea. The coating's purpose was to mimic the good surface properties of standard bentonite-clay bonded pellets; as a benefit, clay consumption was significantly reduced.

The oversize and green balls that are formed and conveyed to conveyors need to be re-circulated leading to increase in re-circulation load. A simulation software can be developed which will control the various parameters by taking feedback during the actual ball formation process (Size, Degree of Compaction etc.) on the pelletizing disc to minimize formation of green balls .

The pelletizing process consists of two main parts: raw pellet (green ball) and product pellet. The raw pellet is obtained by mixing the enriched ore with the binders followed by the agglomeration process, the product pellet is obtained by heating and cooling the raw pellet [ 13 ].

Pelletizing is a method of agglomeration, or particle size enlargement, in which material fines are processed into pellets or granules. Pelletizing is used throughout a multitude of industries to process thousands of materials from difficult to handle powders and fines, into easy to handle pellets.
This mixture is blended together in a mixer and fed to balling discs or drums to produce green pellets of size typically about 9-16mm. The green pellets are then fed to the induration machine. Both straight grates and grate kilns dry the pellets out in a drying section, then bring the pellets up to a temperature of about 800-900 C in a preheat zone, then finish the induration process at roughly 1200-1350 C.
In pelletizing, a mixture of iron ore, water and binder is rolled in a mechanical disc or drum to produce agglomerates (green balls or wet pellets). Green pellets then undergo a thermal process, which consists of three stages, namely drying (250 – 400oC), preheating (900 – 1100oC) and firing (1200 – 1300oC).
Once the green balls are made they are spread out evenly across the grate. The traveling grate provides the means for heat transfer with high, medium and low temperature gases. It utilizes the heat coming from the kiln and cooler to perform this heat recovery.

Since moisture has to be present in the feed material and/or added during the agglomeration process, the resulting agglomerate is relatively soft (green, uncured) and usually requires a secondary process step to dry, cure, or fire the agglomerate and provide finished product strength.

Pelletizing of iron oreEdit. Iron ore pellets are spheres of typically 6–16 mm (0.24–0.63 in) to be used as raw material for blast furnaces. They typically contain 67%-72% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets. Typically limestone,

Green pellets Grate castings 127 – 230 mm Grate-Kiln 250 – Straight-Grate 380 mm 150 mm The green balls formed during the agglom-eration process are then strong enough for transport to the Grate-KilnTM induration ma-chine. There the green pellets are subjected to certain varying process zones of drying,
Pelletizing Process. The sintering process uses the combustion heat of coke breeze (fuel). Pellets are made from iron ore that is finer than that used for sintered ore. The ore fine is formed into spheroids, called green balls, approximately 12mm in diameter. The green balls are fired into product pellets. Contact Us
