Pelletizing discs are used in the agglomeration process to form fine iron ore into uniform green iron ore pellets. Green pellets are feed to a travelling grate or grate kiln.
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.

Jan 01, 2012 The pelletization process is the primary consumer of binders in the iron ore industry. The selection of an appropriate binder type and dosage is of critical importance in producing good quality pellets at a reasonable price. Binders accomplish two very important functions in iron ore pelletization
The location of a pelletizing plant affects the method of receiving raw materials such as iron ore, additives and binders. Many pelletizing plants are located near ore mines. This is because these plants were developed to pelletize the raw materials that are beneficiated at these mines. Such plants receive
Pellet Plant produces Pellets using Iron ore and additives such as limestone, bentonite, coke, anthracite coal, quartzite which are passed through balling discdrum and the green pellets so formed are passed through a furnace either straight grate or rotary kiln to produce High Grade Pellet which are used in Steel
Pellets are made from iron ore concentrates that have an average iron Fe content of at least 60 and particle size of 80 75 m. The concentrate material is mixed with a binder in an intensive mixer, then fed to the pelletizing disc for ballingwhile being moistened by a water spray system. Other materials, such as fluxes, can also be added into the

Feb 23, 2013 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 0.074 mm with additives like bentonite and then shaping them into near ovalspherical balls having size in the range of 8 mm to 16 mm in diameter by a pelletizer and hardening the balls by firing with a fuel.
Iron ore pellet feed nes PFF The iron ore pelletizing process is marked by spherical pellets in a narrow grain size distribution ranging between 9 mm and 15 mm. The raw material in the process consists of iron ore 100 m, binders i.e. bentonite and additives such as coal dust. The moisture of the raw material can be variable.
SCARABAEUS Pelletizing discs guarantees a continuous narrow grain size distribution in the desired size range and a minimal recycling rate. In comparison to a drum with a recy - cling rate of app. 100 to 400 , the rate is extremely low. The specic energy consumption of a disc is 1.0 kWh t iron ore pellets.

The iron pelletizing process is often associated with low grade iron ore following a range of liberation techniques to prepare and make suitable for the blast furnace. In summary, pelletizing is achieved by combining the iron ore with water and a specific binder which is then rolled up in drum to produce relatively uniform pellets which can then be easily handled in downstream processes.
In pelletizing, iron ore, water and a binder are balled in a mechanical disc or drum to produce wet pellets. Bentonite is the most widely used binder in iron ore pelletizing industry.

Process objective is to transform fine iron ore concentrate into pellets suitable to feed Blast Furnace or Direct Reduction plant or COREX. Pelletisation was invented to make use of Blue dust and ultra fine concentrate generated in the Iron ore beneficiation plants. Pellets have the benefit of
Dec 11, 2016 What is pellet The pellets or Iron ore pellets is actually a spherical uniform form of iron ore fines mixed with some ingredients like Dolomite, Bentonite, limestone and coke breeze which are later introduce in a furnace to get high quality iron or steel later. 3
Jan 01, 2012 The ore being pelletized must have a sufficiently fine particle size distribution. Sufficient moisture needs to be added to make the ore sticky enough to pelletize, but not so much moisture that the ore becomes muddy. A binder is required to hold the
The most common filter in the iron ore industry includes 12 discs, 9 feet in diameter, therefore a 1290.20 sq. ft. filtration space 120 m, or 120 sectors of 1 m. The advantages of Metal 7s vacuum disc filters Optional features are available including
Iron ore fines are produced in a rotary kiln in the presence of solid carbon to produce a sponge iron product. The sponge iron product is ground, magnetically separated and pelletized with only hydrated lime and water, and thereafter hardened by heating.

The pelletizing discs used for agglomerating iron ore concentrates into pellets are remarkable for their very narrow particle size distribution with a target size of 10 to 14 mm, important for DR-Processes It is the direct iron ore reduction process, enabled by those uniform size pellets, which finally leads to the tremendous reduction in greenhouse gases. This innovative pellet based solution avoids the
Iron ore pelletizing discs are agglomerators in their essence. We are however interested in their other function, that is of classifiers. The production of pellets inside a pelletizing disc basically relies on two phenomena that occur simultaneously.
This process generates iron ore filter cake which needs to be pelletized to be used in the steel making process. Also during the processing of high grade iron ores which dont need beneficiated, fines which are generated can be pelletized and used instead of being disposed of. Iron Ore Pellets are formed from beneficiated or run of mine iron fines.
characteristics of iron ore itself. Generally, the higher iron content of pellets have the higher reducibility and the higher clustering tendency. Remark Addition of lime hydrated lime or limestone andor dolomite to iron ore results in lower clustering tendency of pellets and
