Iron ore pelletizing Grate-KilnTM system

Iron ore pelletizing 5 Pellet quality Because the induration of the pellets occur in the rotary kiln, the pellets produced in a Grate-Kiln system are consistently of higher quality than those produced in a straight gra-te. The rotary kiln provides constant mixing of the pellets, bringing all the pellets to the same temperature.
