  • Traveling grates - Metso

    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.

  • Straight grate systems - Metso

    Straight grate systems consist of one major piece of equipment. The complete process is done on the grate. The object of the process is to transform the pelletized concentrate into hardened pellets that can be used as blast furnace feed or direct reduction furnace feed.

  • WHAT IS AN INDURATING FURNACE

    In an Indurating Furnace, the pellets are loaded on to a travelling grate to a depth of approximately 3060cm where they are preheated (typically to 800- 9000C), before entering a - higher temperature stage (around 1,200-1,3500C) which in some designs is a continuation of the travelling grate, and in others take the form of a rotary kiln.

  • Traveling Grate Pelletizing Plant - Outotec

    During induration, the green pellets are distributed evenly across the traveling grate and then hardened in a furnace where they pass through updraft drying, downdraft drying, preheating, firing, afterfiring, and cooling zones. Our unique updraft and downdraft drying sequence significantly reduces fuel consumption.
