May Concentrate Iron ore, as a refractory iron concentrate, deteriorates the permeability of sintered layer during sintering process due to its fine particle size and poor granulating performance. Therefore, it cannot be widely used in ore sintering. In this study, strengthening granulation using pre-pelletizing expand utilization ratio was proposed. The experiments conventional granulation, si...

PET bottle waste is easy to recycle because it separate, abundant, and competitively priced. Technologies for the treatment of have been evaluated date by using life cycle assessment (LCA), but this does not take into account all aspects that policymakers consider necessary when selecting an acceptable technology. Aspects such as society, economics, policies, technical applicability need be con...

Grate bar is an industrial part which is used in the indurating furnace of an iron ore pelletizing plant. Steel part ofthe grate bars are expected to have high resistance to atmospheric oxidation because of its contact with hot gases(up to 920 °C) during the normal operation of the process. In this study, different samples from several sections ofused grate bars with apparent ...

Cork industries generate a considerable amount of solid waste during their processing. Its management implies a problem for companies that should reconsider its reuse for other purposes. In this work, an analysis of pelletizing of granulometric separation powder, which is one of the major wastes in cork industries and which presents suitable properties (as an raw material) for its thermal use, ...

Integrated field studies on environmental levels, bioavailability, biological exposure, and effects SUMMARY Iron-ore is the source of primary iron for the world's iron and steel industries. Almost all (98%) iron-ore is used in steelmaking. Australia and Brazil together dominate the world's iron-ore production, while China is the world's largest iron-ore consumer. In Brazil, iron-ore mining is m...

Palm pruning residues are potential pellet raw material, which quite abundant in regions with hot climates. In pelletizing process, material properties and machine features the main factors affecting final quality. this study, 5 mm sieve hole diameter milled palm was pelleted using two different dies moisture. First die (D1) has 25 total length, 17° inlet angle 10 depth. The second (D2) 35 33° ...
