Iron Ore Pelletizing Process: An Overview

depend on each ironmaking furnace and thoserequirements influence the operation ofthe iron ore pelletizing plant. 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

Introduction to Iron ore Pellets and Pelletizing processes

Raw material preparation During the process for pelletization iron ore concentrate from iron ore beneficiation plant is dried and heated to around 120 deg C. 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
