Characteristics of Iron Ore Pellets and Their Influence on Dust Generation Due to Wear

摘要：

　　In the blast furnace process flue dust is generated,which ends up in the off-gases.This results in a loss of valuable raw materials and an increased energy need per produced ton of hot metal.The flue dust also have adverse effects on the environment.Thus,this study is focused on the investigation of the mechanical wear of iron ore pellets.The influence of pellet characteristics,such as size,weight,density and hardness,on the wear mechanism has been investigated.It has been observed that pellets with larger size show a higher wear rate as compared to small sized pellets.Moreover,the dust generated during wear experiments has been analyzed to obtain particle size distributions.
