Traveling grates liming

After feeding the pellets to the traveling grate, the unit operations of green ball drying, concentrate dehydration, partial calcination, and partial induration are performed on a traveling grate, whereupon heat transfer occurs in zones of the grate from the cross flow of process gas (hot air) repeatedly passed through the pellet bed in a modified countercurrent fashion.

Iron Ore Pellets Induration Solutions Metal 7

Iron ore green balls are soft and easy to break. So after the pelletizing and screening operations, iron ore pellets have to be hardened in a furnace through a firing process. Once fired, they can be handled, loaded in ships or trains and delivered to the end users. Two indurating furnace technologies dominate the pelletizing industry, the straight travelling grate and the grate-rotary kiln

Grate kiln systems liming

The Travelling Grate is where pellets are dried and then heated up to a temperature of about 800-900 deg C. The heat used to dry and preheat the pellets is typically hot air pulled from the Kiln and cooler. The recycling of the the hot air from the different zones increases energy efficiencies. In the Kiln, pellets are brought up to final indurating temps. Rotation of kiln exposes entire

KOBELCO Pelletizing Process

Grate-Kiln-Cooler process enables all pellets to be uniformly and adequately heat-hardened by tumbling action and be held at the peak temperature for longer period than in Straight-Grate. a) Uniformity b) Cold compression strength c) Tumble index Iron grade and impurity contents are basically influenced by ore beneficiation processes, but not by the pelletizing process. d) Chemical composition
