KOBELCO Pelletizing Process

iron ore. His process involved grinding taconite to remove gangues and upgrading the iron ore (i.e., an ore beneficiation process). The resultant high-grade ore is in the form of fine particles, as small as 0.1mm or less, which are not suitable for sintering. This issue led to the use of pelletizing. Pelletizing plants are expected to play an

Iron Ore Pelletizing Plant - Iron Ore Pelletizing Pellet ...

Iron ore pelletizing plants play an important role in these two aspects. For low-grade iron ore, they should be beneficiated to improve the iron content. We usually grind up iron ore after mining and remove the useless part (tailings). Therefore, most of the iron ore that is sent into the steel plants has a fine particle size.

Iron Ore Pelletizing Process: An Overview

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. Ballingprocess:thegreenpelletistherolledpelletwithoutanythermalprocess.Itisobtained

(PDF) Sample Proposal for an Iron Ore Pelletizing Plant ...

The preparation of iron ore pellets begins with the crushing and grinding of iron ore into a fine powder, and adding reducing additive coke (C) and binding agents and mixing. The mixture is added to a pelletizing machine or ball mill along with a pre determined amount of moisture to form green pellets. These green pellets are air dried and subsequently oven dried to harden the pellets. Green pellets are fired in a furnace to produce fired pellets

The idea of rolling moist fine ore in a drum to form balls and then drying and firing it was first patented by A. G. Andersson in Sweden in 1912. Further development was performed to bring the idea to reality. In 1943, E. W. Davies and co-workers demonstrated the process using an ...
