granulated iron ore process

Granulated Pig Iron (GPI) International Iron Metallics

The granulation process has four principal steps: control of the flow of hot metal to the granulator; granulation by formation of liquid iron droplets, followed by rapid quenching in water ; discharge of solidified and cooled particles (GPI} dewatering and transport to storage; The diagram above compares the sandpit casting and granulation

Granulation an overview ScienceDirect Topics

L. Lu, O. Ishiyama, in Iron Ore, 2015 14.2.1.3 Chemical characteristics of iron ore. Granulation is generally considered to be a physical process involving the physical interactions of particles mainly through capillary forces. The influence of ore chemical characteristics on granulation is therefore largely neglected in the literature. However, from the authors' experience on deslimed ores

Properties and End-Use Functionality of Iron Ore

Granulated Beds effect on Sinter Properties. The two objectives of this area of research are; to understand the key properties of sinter that control quality parameters such as strength and reducibility; and to understand how sinter quality can be maximized by modifying process conditions and / or iron ore blends, while maintaining productivity and minimising operating cost.

17/1/2019· Granulated iron ore. As you see on the above picture, first iron ore is processed into two groups: granulated iron ore and concentrate. Producing granulated iron ore is done without water (dry). In this process, iron ore, grade of 50%, is crushed in two or three levels and divided into different classes according to their size. Then high-grade iron ores are separated from low ones by physical

Theory and Practice of Sintering of Iron ore IspatGuru

25/11/2018· Granulation is of basic importance for the sintering of iron ore, as good sinter bed permeability largely determines the rate at which the process progresses and hence the productivity of the sinter plant. The granulation of the sinter mix is generally carried out in a rotary drum prior to the sintering process, for several minutes with the addition of 6 % to 8 % of water. The complete

The granulation process also allows for a dust free product for handling, bagging and transportation. In addition to working with powders, for certain applications, the mixer can act as a rough milling device, using the high speed rotor to break down non-uniform or lumpy materials into a powder in order to build the material back up into a granule.
