    The rotary kiln provides 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

The capacity of the kiln depends on metallization degree and usually does not exceed 225,000 – 300,000 t/y. It is operated in counter-current flow with solids moving down the incline in opposite direction to the gases. Iron ore and coal are jointly charged to the kiln from the
