| Abstract: | Using Brazil hematite concentrate as the major raw materials,based on systematic study on characteristics of hematite for production of oxidized pellet,and in view of problems like poor green ball strength,high roasting temperature and poor product pellet strength,the effect of high pressure roller grinding pretreatment on balling performance and roasting performance and its rule were studied systematically,and influencing mechanism was analyzed from the view of the particle shape.After pre-treatment,the sp... |
| Keywords: | high pressure roller grinding hematite concentrate oxide pellet particle shape |
