Pelletizing is a process, in which fine disperse granular materials, e.g. iron ore concentrates or fly ash, are agglomerated to form larger particles during the 1 Introduction. Agglomeration is a common process in steel manufacturing industry. Fine iron ore is fed into a disk pelletizer and sprayed by water.

The iron ore concentrates and different binders (bentonite, lime, limestone, and Cement) are mixed in calculated proportions and placed in a disk pelletizer with a 1 m diameter for pelletizing. The ratio of iron ore concentrates and binder mixture for different pellets is shown in Table 3. The disk angle and speed of the pelletizer are fixed asThe influence of agitating conditions on agglomeration and collapse of wet iron ore mixture was inves-tigated in the view of kinetics and matrix model analysis.

Johnson–Kendall–Roberts (JKR) model is one of the most commonly used cohesive models (Johnson et al., 1971). Though the JKR model is straightforward and unable to reproduce the history dependence behaviour of particles, it is still suitable in the discussion of the physical mechanism of granular materials (Roessler and Katterfeld, A polynomial regression equation was used to quantify the characteristic curve of iron ore slimes agglomeration process.

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 ].Perhaps the two most common devices used are the disc pelletizer (also known as a pan granulator) and rotary drum.

Disc pelletizer is widely used in the agglomeration process to form powdered iron ore into iron ore green pellets. The pellet size distribution (PSD) is one of the major measures of product quality. An imag-ing system is developed for measuring PSD in the stable area of the disc pelletizer.

In particular, the drum type of iron ore pelletizer is analyzed as a two input/two output control system. The first phase of this analysis concerns the modelling of the basic mechanisms of agglomeration, this leads to a stability study aimed at overcoming certain operational difficulties associated with drum pelletizers.2) Pelletizing on a disc pelletizer. The conditioned material enters the pan, and as the pan rotates, the iron ore tumbles against itself, growing in size.

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.Abstract. 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 feed, inorganic and organic binders, and new additives.

The green pellet size range for the three iron ore samples was optimized on the basis of disc inclination, disc rpm and retention time of pellet on the disc pelletizer. As per the commercial applications, the average size of the fired pellets is suggested to be in the range of 10–12 mm (> 80%), however during heat-hardening process of greenThe Direct Reduction of Iron.
