Besides iron ore agglomeration these pelletizers can also be used for other materials such as copper ore gold ore coal and fertilizer 12. The rotary drum pelletizer was first used for taconite pellets in the early 1940s 14 18 .
Build-up agglomeration is a well-established method for manufacturing granules or pellets from powdery mineral raw materials. Companies regularly have to ask themselves what the best easiest and most cost effective way is to manufacture their required products. Mixers disk pelletizers and pelletizing drums are available for build-up agglomeration.
Clariant Mining Solutions has developed specific binders for the iron ore pelletizing industry that enhance the agglomeration process of iron ore fines. Our FLOTICOR PA series upgrades the pellet mechanical properties thus producing more cohesive pellets that are less fragmented or cracked.

Iron Ore Agglomeration Processes and their Historical Dec 28 2015 Pelletizing of iron ore is a method of Swedish origin patented in 1912 by AG Andersson Yamaguchi et al 2010 The process was developed in the USA in the 1940s and the first commercial plant started operation in Babbitt Minnesota in 1952 iron ore pelletisation kiln
Iron ore pelletizing or balling is the process of transforming fines into spherical granules anywhere from 8 – 16mm in size via tumble-growth agitation agglomeration using either a disc pelletizer pan granulator or rotary drum.
Jan 01 2012 Pelletizing differs from other agglomeration techniques in that the powdered ore is first formed into a green pellet or ball which is then dried and hardened in a separate step usually by heating. Green pellets are made by combining moist ore with a binder and rolling it into balls using either a pelletizing disk or a pelletizing drum.
Jul 10 2017 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 low-grade 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
Jun 04 2019 This work has found that the same organic binder performs differently depending on the type of iron ore processed. KEYWORDS: Pelletizing iron ore binder agglomeration interaction Additional information
L Lu O Ishiyama in Iron Ore 2015 Abstract Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use In this chapter the sintering process is first described and the key steps of the sintering process namely granulation and thermal densification are identified . more.
Machine sintering and pelletizing iron ore. Iron Ore Agglomeration Processes and their Historical . Dec 28 2015Though a large numbers of improvements have been made since then in the machine mechanical design and in the process of iron ore sintering still the basic principle of the process remains the same History of pelletizing Pelletizing ...
Oct 30 2020 Circular Pelletizing Technology The ever-higher portion of fine and ultrafine iron ore from mining sites means that the pelletizing process is becoming more important for ore agglomeration. This has led to an increased interest by steel producers to invest in their own pellet plants to become independent of changing prices for pellets on the ...
Pelletizing Agglomeration - Expertise - Process and Metallurgy. The agglomeration is a process which uses fine particles added with ... This process is mainly used to produce iron ore pellets which supply the blast furnaces.
Pelletizing discs. Pelletizing discs are 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 stop the disc adjust the speed of the disc with a potentiometer and view the

Scarabaeus pelletizing discs provided by HAVER amp; BOECKER NIAGARA are used for sustainable and efficient production of iron ore pellets. The unit’s design minimizes circulation increasing productivity and profitability. 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 ...
Technologies for the agglomeration of fine-grained iron ores including 60 years’ experience in supplying traveling grate pelletizing plants. Globally we have delivered more than 65 plants for a wide range of ore types. Our traveling grate indurating process is responsible for two thirds of the world’s installed pelletizing capacity.
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.
The decline in the availability of high-grade iron ore has driven the development of fine particle agglomeration processes to meet the demands of blast furnaces. The diminishing number of high-grade ore deposits also led to the mining of lower-grade deposits including taconite deposits that had previously been ignored.
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
