Abstract

In this paper, the method of preparing green balls from Brazilian iron concentrate was studied. The hematite and two kinds of magnetite concentrate were the main raw materials, the effects of the dosage of bentonite, pelletizing moisture, pelletizing time, particle size, and the ratio of the two magnetite concentrates on the green balls’ strength were studied. When using 1.0–1.3% Indian bentonite, the pelletizing moisture of 9.5–10%, the pelletizing time of 12–15 min, the mineral powder particle size under the condition of −325 mesh 85–90%, it is suitable for pelletizing. And the falling strength of the green balls is 3.0 times 0.5 m−1, the compressive strength is 16–23 N/P, the decrepitation temperature of the green balls is above 350 ℃. After blending with the magnetic concentrate, the decrepitation temperature of the green balls rises, but the strength decreases, and the amount of bentonite needs to be increased.
