Because the induration of the pellets occur in the rotary kiln, the pellets produced in a Grate-KilnTM system are consistently of higher quality than those produced in a straight grate.
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.
