磁铁矿粉与您分享：我们确实有如是的优点，但也要隐藏几分，这个叫做涵养。
    磁铁矿粉分布广泛，特别是在南美地区，那里的磁铁矿粉纯度较高，是优质的磁铁矿粉。特别是

秘鲁的磁铁矿粉。
    秘鲁磁铁矿粉具有粒度细、品位高、脉石含量低等优点,但其碱金属含量相对较高,且二氧化硅含

量过低,容易引起球团矿还原膨胀率高等问题,而且放置时间较长的秘鲁矿粉成球性能下降,影响造球和

生球质量。通过试验,研究了秘鲁矿粉的造球性能,以及地方矿粉和含镁熔剂对秘鲁矿粉球团造球、焙

烧及成品球质量的影响。试验结果显示,采取高压辊磨、配加地方矿粉或含镁熔剂等措施可以改善秘鲁

矿粉的成球性能和生球质量。秘鲁矿粉配加二氧化硅含量较高的地方矿粉或添加蛇纹石、橄榄石等含

镁熔剂,能有效控制球团矿的还原膨胀率。
    Magnetite powder to share with you: we do have such advantages, but also want to

hide, this is called conservation.
    Magnetite powder is widely distributed, especially in South America, magnetite powder

with high purity is there, magnetic-breeze quality. Especially magnetite in Peru.
    Peru magnetite powder with fine granularity, high grade, gangue content is low, but

its alkali metal content is relatively high, and the silica content is too low, easy to

cause the pellet swelling ratio higher, and placed a long time Peru ore balling

performance, influence of granulating and quality of green ball. Through the test,

research the Peru ore balling performance, as well as the influence of local ore powder

and magnesium fluxes on Peru powder pelleting, roasting and finished product ball

quality. The test results show, take the high pressure roller mill, with local ore powder

or magnesium flux measures can improve the performance and quality of green ball ball

into the Peru iron ore. Peru ore with higher silica content in the local iron ore or the

addition of serpentine, olivine containing magnesium fluxes, energy reduction swelling

rate of effective control of pellets.
