Bentonite for Iron Ore Pelletization, absorbent, expandable Iron Ore Pelletizing Industries Binders improve pellet green strength in the production of iron ore concentrate pellets. And the one that solves the purpose is Sodium Bentonite clay, which has higher water plate absorption along with superior Thermal Stability. Elements–Binder
To the iron ore fines, 0.5-3.0% bentonite is added as a binder. Coke breeze and some flux (limestone) may also be added. The mixture is placed in cones, drums or discs, out of which discs are relatively more flexible with regard to types of ore and they can be controlled better. A disc pelletizer is a rotating inclined flat plate table.

Bentonite for Iron-Ore Pelletizing. Bentonite is used as a binding agent in the production of iron ore pellets. Through this process, iron ore fines are converted into spherical pellets, suitable as feed material in blast furnaces for pig iron production, or in the production of direct reduction iron (DRI)
Dry bentonite's specific gravity is around 2.4 - 2.8. Bentonites tend to break quickly into very small particles when in water dispersions. Wyoming Sodium bentonite provides 60-65% particles smaller than 0.1pm, around 90% particles are finer than …
Iron ore pellets and Pelletizing processes. Pelletizing is a process that involves mixing very finely ground particles of iron ore fines of size less than 200 mesh with additives like bentonite and then shaping them into oval/spherical lumps of 8-16 mm in diameter by a pelletizer and hardening the balls by firing with a fuel.

Pelletizing, or balling, carried out through either a disc pelletizer or rotary drum, is a key part of efficiently and sustainably producing steel from iron ore fines of varying sources. FEECO is a leader in feasibility testing, custom disc pelletizers and balling drums, and parts and service support for the iron ore balling/pelletizing industry.
The present invention refers to a binding composition containing bentonite for use in binding finely ground iron ore. The composition of the invention comprises bentonite and molasses. The invention also refers to process for preparing iron ore pellets wherein a composition comprising bentonite and molasses is used as binder.
Due to its water absorption capacity and colloidal property, bentonite is used as a binding additive to convert iron ore fines into pellets Through this process, iron ore fines are converted into spherical pellets, suitable as feed material in blast furnaces for pig iron production, or in the production of direct reduction iron .
When bentonite content is 1.5% and 1.3%, the falling strength of the green pellet improved compared with those of green pellets that contain 1.0% bentonite. Increasing homogeneous bentonite content from 1.5% to 1.0% gradually decreases the falling strength from 3.00 times/pellet to 2.53 times/pellet.
Mikolit® is a sealing pellet which requires no mixing or pumping. It is a patented clay based pellet with a very low dust content. Mikolit300 is a medium grade bentonite pellet suitable for most applications. It has a swelling capacity of 50-70%. All Mikolit pellets have excellent sinking qualities and are dust free and easy to use.

Iron Ore Pelletizing Bentonite. While activated calcium bentonites swell about 5-6 times of their volume, Sodium bentonites can swell up to 25-30 times. Swelling is directly influenced by the Enslin value required for the pellet. The water, which can locate between each layer of montmorillonite and be connected with the forces of Van der Walls ...
Bentonite is an effective, widely used binder in the iron ore pelletizing process. Its low price is an important factor for its extensive use. However, bentonite incorporates silica and alumina, which are undesirable contaminants to pellets. Additionally, it is a natural material with variable composition depending on its origin.
Iron Ore. Much of the world's supply of iron ore is produced from a hard rock called taconite, which is ground to a very fine powder to produce iron ore concentrate. KM's IOP GRADE BENTONITE is added to the iron ore concentrate to act as a binder, facilitating the formation of iron ore pellets. The pellets are then fed to the blast furance for ...

Iron ore pellet strength data of pellets made with 0.33% (7 lb/lt) bentonite which is half of the typical dosage. Longer mixing times give little or no improvement in pellet strength. However, the type of mixing does, as shown by the increase in pellet strength with additional passes through the roll press.
Stockpiling activated Khakassian bentonite in accordance with Technical Specification for Iron ore pelletizing plant (IOP). The use of Dash - Salakhlinskoye bentonite in the charge materials contributes to the production of pellets with a low damage ratio at high-temperature firing process and their high fracture resistance due to thermal stresses.
While the bentonite addition decreased, the drop number and thermal shock temperature of green balls improved by 0.9 times/0.5 m and 150 °C, respectively. This has resulted in an improvement in the overall iron grade of fired pellet by 1.02% and in CCS by 1000 N per pellet (Liu et al., 2005; Zhu et al., 2009).
Bentonite referred to as either "Calcium Bentonite" or "Sodium Bentonite" is generally one of the most multi-functional minerals. Basically, the inherent physical properties in Bentonite provide a wide range of industrial applications and since the Middle East is specifically rich in this mineral resource; therefore you can locate the best quality of varied grades of Bentonite in here.
possible to make pellets which meet the standards by adequate addition of type and amount of bentonite. Keywords: bentonite, pelletizing, iron ore concentrate, binder, sodium bicarbonate Introduction Major raw material in iron and steel industry is iron ore which can be classified as high grade and low grade in terms of its Fe content.
Bentonite is the most widely used binder in iron ore pelletizing. The use of bentonite is favorable in terms of physical, mechanical and metallurgical pellet qualities, however, because of its acid constituents (SiO 2 and Al 2 O 3) it is considered as an chemical impurity especially for concentrate with high SiO 2 content.
