Effect of Grinding Method (HPGR & Dry Ball Mill) on Iron Ore Pellet Quality | As particle size and shape has an important effect on green and fired pellet quality, HPGR and Dry Ball Mill, as the two important grinding methods in iron ore pellet plants responsible for particle's size and shape, were used to investigate the effect of particle .
Direct-reduced iron has about the same iron content as Pig Iron, typically 90–94% total iron (depending on the quality of the raw ore) as opposed to about 93% for molten pig iron, so it is an excellent feedstock for the electric furnaces used by mini mills, allowing them to use lower grades of scrap for the rest of the charge or to produce .
