Iron powder briquetting equipment main used to press iron powder then used for smelting, pellets ore main raw material is ore powder, generally speaking, there are two methods to process final products output from ore beneficiation, using briquetting plant for sale pressed final briquettes and high temperature sintering improve the property, their names are pellets ore and sintering ore, while they have absolutely different features:
1)Different size: pellets ore suit for fine grinded ore powder briquetting, sintering ore suit for coarse size ore powder, when fine ore used for sintering after ore beneficiation, material layer with bad breathability, it will effect sintering ore production capacity and quality, thus, you should using metal powder briquette machine and other equipment to take pressing process make it to ball briquettes. While coarse size ore powder and crushed coke, rolling paper, blast furnace dust and other difficult to briquetting industrial waste will suit to produce sintering ore.
2)Metallurgical properties: from most metallurgical properties to compare, pellets ore is better than sintering ore, briquettes with uniform granularity, high iron content, reproduction is good, low temperature condition with good strength. Small pellet ore stomatal degree, benefit for improve refined products strength and reproduction property, when using briquetting equipment output briquettes to smelt, all of them can improve the production capacity, decrease coke rate, but the final products quality has relative on the smelting condition.
3)Transport and storage: pellets ore output products by briquette machine processed has good strength in normal temperature, during transport process with less crush and suit for long times storage, while sintering ore during long times storage will easy lost strength. During the production process, as pellet ore when calcination material layer with good breathability, high strength, compared with sintering ore can reduce escaping dust to air and benefit for improve the environmental condition.
4)Hot reductive property: pellets ore hot reductive property is worse than sintering ore, but pellets ore with high silica content is benefit for improve pellets ore hot reductive strength. When using powerful ore powder briquette machine press ball briquettes to smelt, if there are a certain amount of potassium and sodium oxide in ball briquettes can accelerated reduction iron oxide, increase volume expand when reductive, suit improve calcination temperature will increase ball briquette liquid bond and improve hot reductive strength.
