Introduction to Iron ore Pellets and Pelletizing processes ...

The dried material is fed to the ball mill for grinding. Concentrate/ground iron ore of typical size 80 % less than 45 microns (0.045 mm) with a moisture content of around 9 % is required for the pellet production. Suitable binder (normally bentonite) is added to the concentrate which is thoroughly mixed in high intensity mixer. Formation of green balls or pellets – Green pellets

Understanding Pellets and Pellet Plant Operations –

21/03/2015  The process of enriching taconite ore involved grinding the ore 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 0.1 mm or less, which are not suitable for sintering. This issue led to the development of the pelletizing process.

Iron Ore Pelletizing Process: An Overview

Bentonite is an effective, widely used binder in the iron ore pelletizing process. Its low price is an important factor for its extensive use. However, bentonite incorporates silica and alumina, which are undesirable contaminants to pellets. Additionally, it is a natural material with variable composition depending on its origin. Obtaining a suitable binding effect requires a relatively large ...

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 ...
