Iron ore pelletization process using a rotary drum pelletizer. Disc pelletizers are also used extensively worldwide. The advantage of the disc pelletizer is that there is no recirculation. The desired blend is fed to the pelletizer, which is a large disc inclined at 40–60° to the horizontal ( Figure 1.2.7 )

image-based method for measuring pellet size distribution

Disc pelletizer is widely used in steel manufacturing industry in the agglomeration process to form powdered iron ore into iron ore green pellets. The raw material is fed into the disc and sprayed by water . With continuous rotation of the disc, fine particles are gathered and formed into larger pellets in the stable area, finally falling out of the disc as green pellets

Nov 26, 2014 · Iron Ore Pellets and Pelletization Process. Pelletizing of iron ore was started in the 1950s to facilitate the utilization of finely ground iron ore concentrates in steel production. For the pelletizing of iron ore there are two main types of processes namely, the straight travelling grate (STG) process and the grate kiln (GK) process

Assessment of iron ore pellets production using two charcoals with . Iron ore pelletizing plant consumes coal, pet coke, oil and natural gas to get iron ore pellets, which consumed natural gas; coal (anthracite fines) and two CHAR2, CHARPY1 and CHARPY2, were all ground in pilot ball tube mill. The details of pelletizing disk are as follows

Our heavy-duty iron ore balling drums are relied on by some of the industry’s top producers to process iron ore fines into pellets for the steelmaking process. The use of a disc pelletizer is a popular alternative approach to pelletizing iron ore fines, as this offers more control over pellet size and produces a more refined pellet product. Additionally, this approach offers significantly less recycle than a balling drum …

Sep 22, 2013 · The process of pelletizing iron ore on disc pelletizers is mathematically modeled. Different methods of regression analysis are used to describe the pelletizing operation, and the equations that are obtained are compared with one another. The objective function is optimized based on the yield of green pellets of the class (–14+5) mm

optimizing the operation of straight-grate iron-ore pellet

optimizing the operation of straight-grate iron-ore pellet

Mathematical models of straight-grate pellet induration processes have been developed and carefully validated by a number of workers over the past two decades. However, the subsequent exploitation of these models in process optimization is less clear, but obviously requires a sound understanding of how the key factors control the operation. In this article, we show how a thermokinetic model of pellet induration, validated against operating data from one of the Iron Ore …
