    The temperature profile in the kiln is controlled by radial air ports in thepreheating zone, and axial air ports in the reductionzone. The product is cooled in a rotary cooler, and screened and magnetically separated to recover the DRI and char. DRI fines are briquetted, and the char is recycled to the kiln to increase fuel efficiency.

    Therotary kilnprovides constant mixing of the pellets, bringing all the pellets to the same temperature. In a straight grate, the pellets at the top of the bed are “over cooked” and those at the bottom are “under cooked”. Higher quality means fewer fines, better reducibility and less variation in compression strength.
