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.
