Iron Ore Green Pellet Characteristics

Jan 01, 2012 Iron ore fines are mixed with pulverized coal, agglomerated into green pellets. The pellets are fed to an RHF, heated to 16231723 K, and reduced, melted in the RHF within approximately 10 min and then discharged. The gangue and ash contained in the pellets are melted to separate metallic iron and slag in the RHF.

Compression Testing of Green and Dry Iron Ore Pellets

Table of ContentsMaterials and EquipmentGreen Pellet TestingDry Pellet TestingEffect of Test Variables For many years the green and dry compressive strengths of pellets have been considered as possible criteria of pellet performance during induration.

GF88 is a truly green mineral product. It enjoys high iron content, low impurities and low loss-on-ignition characteristics. It also deploys a unique, innovative and environmental-friendly production process, which has no need for heating or water and generates no tailings.

JP2000087149A Production of iron ore pellet Google

At the time of preheating treatment of a green pellet, the liquid-phase sintering of the iron ore powder, is executed. The additive is reacted with the iron ore to produce the low m.p. compound, and this low m.p. compound develops a liquid-phase sintering at the contacting points among the iron ore particles and the iron ore particles are joined.

Variables Affecting Iron Pellet Properties

Variables Affecting Pellet Properties Pellet making is a complex process, requiring careful attention to the successive stages of feed preparation, balling, drying, firing, and cooling. Thus although the properties of the finished pellets are developed during the thermal induration or firing stage, the firing time and temperature are not the only variables which affect pellet properties. Ore ...
