Iron Ore Pelletizing. As one of the main components of ironmaking equipment such as blast furnaces, iron ore pellets affect the efficiency of these processes. Having a uniform size range and open pores iron ore pellets has a lot of advantages like a high mechanical strength resulting in good transporting possibilities or a good permeability.
Study of cold bonding pellets in laboratory. 1) Raw materials – iron ore ground to desired size (85% -200 mesh) is pelletized by a pelletizing disc with a diameter of 1000mm. The chemical components of raw materials used are shown in Table 1. 2) Results of experiments. a) Storage method of green pellets – Green pellets reach the desired ...
About Iron Ore Pelletizing (Balling) Pellets are a high-grade source of iron ore and are produced via a type of agitation agglomeration (wet granulation or tumble-growth agglomeration) known as pelletizing, and referred to in the iron ore sector as "balling.". The balling process is carried out utilizing either a rotary drum or disc ...
We've been building disc pelletizers since 1951. Our pelletizers are designed and fabricated to the highest quality standards, and built to meet tough applications. We also offer a unique lab facility that can help you determine if …
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 ...
Agglomeration is the process of converting iron ore fines into easily handled size and shapes as required in blast furnaces [1]. In the …
Process 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. Applications Pelletizing discs are used in iron and steel …
Top charging of mostly reduced iron ore pellets is readily represented in our automated spread sheet calculations. The steps are; 1. calculation of DRI pellet enthalpies at 25°C and 930°C, the top-segment–bottom-segment division temperature; 2. specification that the DRI pellets are not oxidized nor reduced while descending through the top ...
The PLD pelletizing disc is designed to produce suitible pellets made of mnerals or iron ore. ... The PLD pelletizing disc is suited for iron ore and minerals. Eliminating the conventional gear rim/pinion drive makes this design extremely low-maintenance and highly robust for continuous industrial use. ...
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 ... drive design, it is possible to start the disc fully loaded. To influence the product quality and to meet changing operation
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 fine-grained iron ore concentrates, it is necessary to agglomerate these concentrates. Pelletizing of iron ore concentrates in pelletizing discs leads to significant tighter distributed pellets with smooth surface. Pelletizing – How? The process chamber of a pelletizing disc is made by an inclined, rotating, flat cylindrical pan. Due ...
EXPANSION AND MODERNIZATION OF AN IRON ORE PELLETIZING PLANT IN NORTHERN SWEDEN M. Ahrens, ABB Switzerland, Baden-Dattwil, Switzerland Abstract The paper describes the main drive systems of an iron ore pelletizing plant and related important design aspects. It is shown how today's drive systems provide the desired flexibility for the process and
A brief introduction to recent developments in iron ore pelletizing is provided in this chapter, including the world output of fired pellets, pellet production processes, preparation of pellet ...
LIFTER LINER (4 ROWS AT 60°) 4°inclined Liners inside drier. 26. Wear mapping of pelletizing disc 26 This area is continuously in contact with the radically outwards moving green pellets. This can reduce life of disc. Discharge chute This is used to discharge the green pellets to bins and hence always in contact with pellets.
Uniform pellets for a more consistent product. Features. Used in the agglomeration process to form fine iron ore into uniform green iron ore pellets. State-of-the-art operators control station allowing operator to locally start and …
technology installed in a pelletizing disc or drum. Based on the measurement data the plant's process control system can optimize the rotation speed of pelletizing discs/drums and the feed rate in real time. The performance of an induration furnace is heavily determined by the gas permeability in the pellet bed.
Solid and compact. Agglomerates are the hidden companions of our day-to-day life. Everyday we use a multitude of products from different industries all produced with the help of agglomeration technology. With reference to …
11 The WOGEMA PLD Pelletizing Disc is suited for iron ore and minerals. Eliminating the conventional gear rim/pinion drive makes this design extremely low-maintenance and highly robust for continuous industrial use. Technical details Solid design for continuous operation under industrial conditions Same compact construction for each size
Iron ore must be shipped in bulk for maximum economy. 1.2 Pretreatment process In this process, the iron ore is ground into fines having qualities required for the subsequent balling process. The pretreatment includes concentrating, dewatering, grinding, drying and prewetting. In general, low-grade iron ore is ground into fines
Iron ore products classification for ironmaking [ 3 ]. Pellets are balls formed by rolling moist concentrates and fines iron ores of different …
The pelletizing discs are HAVER® PELLETIZING DISCS are is also adjustable. Due to the sophis- equipped with static scrapers to en- maintenance friendly due to their ticated drive design, it is possible to able …
Pelletizing disc is the most commonly used balling equipment in iron ore pelletizing plants. Materials on pelletizing disc are mixed with an appropriate amount of water to be processed into green pellets. Once pellets have reached the desired size, they leave the pelletizing disc and proceed to the next step.
FEECO's Disc Pelletizers (also known as pan granulators) are the equipment of choice for converting powdered materials into uniform, round pellets. Disc pelletizers utilize a non-pressure (tumble growth) approach to agglomeration …
Generically, the iron ore products for ironmaking can be classified as shown in Table 1 . Pellets are balls formed by rolling moist concentrates and fines iron ores of different mineral- ogical and chemical composition, with the addition of additives and binder, in a horizontal drum or in an inclined disc [1, 4].
